For ‘idli-vada’ to first occur after 50, the two numbers must have an LCM exceeding 50 but less than 60. Numbers under 10 with this property are 6 and 9, whose LCM is 54. The LCM is calculated as (6 × 9) ÷ 3 = 54, where 3 is their greatest common divisor (GCD). Thus, the first shared multiple afterRead more

To reach both treasures, the jump size must divide both 28 and 70. The factors of 28 are 1, 2, 4, 7, 14, and 28, and the factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The common factors are 1, 2, 7, and 14. Among these, 14 is the greatest common divisor (GCD), ensuring it is the smallest jump siRead more

The least common multiple (LCM) of all numbers from 1 to 10 is 2520, found by considering their prime factorizations. To exclude 7, divide 2520 by 7, yielding 360. This number is divisible by all integers from 1 to 10 except 7, satisfying the condition. The prime factorization of 360 further confirmRead more

This number is divisible by all integers from 1 to 10 except 7, satisfying the condition. The prime factorization of 360 further confirms this: 360 = 2 × 2 × 2 × 3 × 3 × 5, excluding 7 as a factor.
To determine the smallest number that is a multiple of all numbers from 1 to 10, compute their least common multiple (LCM). Using prime factorizations, we find that 2, 3, 5, and 7 must be included with appropriate powers. The LCM is 2520, derived from 2³ × 3² × 5 × 7. This number is divisible by eveRead more

Using prime factorizations, we find that 2, 3, 5, and 7 must be included with appropriate powers. The LCM is 2520, derived from 2³ × 3² × 5 × 7. This number is divisible by every integer from 1 to 10, confirming it as the smallest common multiple for this range.
Between 21 and 30, the prime numbers are 23 and 29, totaling 2. These numbers have no divisors other than 1 and themselves. The remaining numbers (21, 22, 24, 25, 26, 27, 28, and 30) are composite, totaling 8. Composite numbers have additional divisors, like 24 (divisible by 2, 3, 4, 6, 8, and 12).Read more

Anshu and his friends play the idli-vada game with two numbers smaller than 10. The first time anybody says ‘idli-vada’ is after the number 50. What could these two numbers be?
For ‘idli-vada’ to first occur after 50, the two numbers must have an LCM exceeding 50 but less than 60. Numbers under 10 with this property are 6 and 9, whose LCM is 54. The LCM is calculated as (6 × 9) ÷ 3 = 54, where 3 is their greatest common divisor (GCD). Thus, the first shared multiple afterRead more
