Question

find the hcf of the pair of numbers 105 and 120​

Answer 1

Answer:

By applying Euclid’s division lemma on 120 and 105 we get, 120 = 105 x 1 + 15. Since remainder ≠ 0, apply division lemma on divisor 105 and remainder 15 105 = 15 x 7 + 0. Therefore, H.C.F. of 105 and 120 is 15.

Answer 2

Answer:

GCF = 15

Step-by-step explanation:

for the values 105, 120

Solution by Factorization:

The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105

The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

Then the greatest common factor is 15.
