2. Find all the factors of 72.

3. Find the prime factorisation of 840.

4. Find common factors of 44, 66. Then find its H.C.F.

5. Find LC.M. of 6, 8, 10 by prime factorisation method​

Answer 1

1) 10101

2), 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72 are the factors of 72

3)840 is 23 × 31 × 51 × 71

4)factors of 44 = 1, 2, 4, 11, 22, 44; factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66

5)2^3 × 3^1 × 5^1= 120.prime factorization is 120
