Leap years are those divisible by 4 but not by 100, unless also divisible by 400. For someone born in 2000, the leap years include 2004, 2008, 2012, 2016, 2020, and 2024. Class 6 Mathematics Chapter 5 Prime Time question answer Class ...
This statement is always true. The sum of two odd numbers is always even, and when two odd numbers are added, their remainders modulo 4 sum to 4, ensuring divisibility by 4. Class 6 Mathematics Ganita Prakash Prime Time Class 6 Mathematics ...
This statement is sometimes true. For example, 2 + 2 = 4 (a multiple of 4), but 2 + 6 = 8 (not always divisible by 4). It depends on the specific even numbers. Class 6 Mathematics Ganita Prakash Prime Time Class ...
The smallest number is 2520. It is the least common multiple (LCM) of the numbers 1 to 10, calculated using their prime factorizations: 2ยณ ร 3ยฒ ร 5 ร 7 = 2520. Class 6 Mathematics Ganita Prakash Prime Time Class 6 Mathematics ...
The smallest number is 2520 รท 7 = 360. The least common multiple (LCM) of numbers 1 to 10 is 2520. Excluding 7, dividing 2520 by 7 gives the smallest valid number, 360. Class 6 Mathematics Ganita Prakash Prime Time Class 6 ...
Co-prime pairs are: Co-prime numbers are two numbers that share no common factors other than 1. Their greatest common divisor (GCD) is 1. Examples include (8, 15) and (21, 22), which have no shared prime factors. (18, 35): GCD = 1 (15, ...
The smallest 4-digit palindrome divisible by 4 is 2002, and the largest is 9999. Both numbers meet the conditions for divisibility and being palindromes when checked through divisibility tests. class 6 Mathematics Textbook Chapter 5 question answer class 6 Mathematics Chapter 5 ...
A number is divisible by 4 if the number formed by its last two digits is divisible by 4. For example, 132 is divisible by 4 because 32 (the last two digits) is divisible by 4. Between 1730 and 1740: ...
