Find the HCF AND LCM OF ALL THE FOLLOWING GIVEN NUMBERS:
540,1140
462,378
360,2100
336,882
924,126

Answer 1

15

Explanation:

Prime factorization of the numbers:

330 = 2 × 3 × 5 × 11

75 = 3 × 5 × 5

450 = 2 × 3 × 3 × 5 × 5

225 = 3 × 3 × 5 × 5

LCM(330, 75, 450, 225)

= 2 × 3 × 3 × 5 × 5 × 11

= 4950

GCD(330, 75, 450, 225) = 15
