To find multiples of 25 that are not multiples of 50, list multiples of 25 (25, 50, 75, 100, 125, etc.) and exclude those divisible by 50 (50, 100, etc.). The remaining numbers include 25, 75, and 125, which satisfy the condition. Each of these is divisible by 25 but not by 50, as their divisibilityRead more

The remaining numbers include 25, 75, and 125, which satisfy the condition. Each of these is divisible by 25 but not by 50, as their divisibility excludes even multiples of 50.
Two numbers under 10 with an LCM exceeding 50 are 7 and 8. Their LCM is calculated using the formula LCM(a, b) = (a × b) ÷ GCD(a, b). Here, 7 and 8 have no common factors besides 1, making their GCD 1. The LCM is thus (7 × 8) ÷ 1 = 56. This exceeds 50, meeting the condition while ensuring the indiviRead more
