Write two numbers whose product is 10000. The two numbers should not have 0 as the units digit.
To find two numbers whose product is 10000 without a 0 in their units digit, consider: • 25 and 400: 25 × 400 = 10000. Both end in non-zero digits (5 and 4), fulfilling the condition. While the product must equal 10000, ensuring no trailing zeroes in the individual numbers' digits limits valid combiRead more

Find numbers between 330 and 340 that are divisible by 4.
To identify numbers divisible by 4 between 330 and 340, test each number for divisibility. Starting from 330: • 330 ÷ 4 = 82.5, not divisible. • 332 ÷ 4 = 83, divisible. • 336 ÷ 4 = 84, divisible. • 340 ÷ 4 = 85, outside the range. Thus, 332 and 336 are the only numbers in this interval that divideRead more

Find the largest and smallest 4-digit numbers that are divisible by 4 and are also palindromes.
The smallest 4-digit palindrome divisible by 4 is 2002, found after testing smaller palindromes for divisibility. Similarly, the largest 4-digit palindrome divisible by 4 is 9999, meeting the symmetry and divisibility conditions. Verifying divisors ensures no false inclusions or exclusions occur, paRead more
The smallest 4-digit palindrome divisible by 4 is 2002, found after testing smaller palindromes for divisibility. Similarly, the largest 4-digit palindrome divisible by 4 is 9999, meeting the symmetry and divisibility conditions. Verifying divisors ensures no false inclusions or exclusions occur, particularly as the symmetry constraints require careful handling of the specific numeric properties concerning modularity and arithmetic parity.

Which of the following pairs of numbers are co-prime? (18, 35), (15, 37), (30, 415), (17, 69), (81, 18).
Using prime factorizations: • (18, 35): Factors are 2,3 and 5,7; GCD = 1, co-prime. • (15, 37): Factors are 3,5 and 37; GCD = 1, co-prime. • (30, 415): Factors are 2,3,5 and 5, 83; GCD = 5, not co-prime. • (17, 69): Factors are 17 and 3, 23; GCD = 1, co-prime. • (81, 18): Factors are 3⁴ and 2,3²; GCRead more
Using prime factorizations:
• (18, 35): Factors are 2,3 and 5,7; GCD = 1, co-prime.
• (15, 37): Factors are 3,5 and 37; GCD = 1, co-prime.
• (30, 415): Factors are 2,3,5 and 5, 83; GCD = 5, not co-prime.
• (17, 69): Factors are 17 and 3, 23; GCD = 1, co-prime.
• (81, 18): Factors are 3⁴ and 2,3²; GCD = 9, not co-prime.
Not co-prime numbers are two numbers that share common factors other than 1. Their greatest common divisor (GCD) is greater than 1. Examples include (8, 12) and (14, 28), sharing factors like 2 or 7.
