Given numbers are 870, 120, 901, 756

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 901 are 17 x 53

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 870, 120, 901, 756

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(870, 120) = 3480

GCD(870, 120) = ( 870 x 120 ) / 3480

= 870 / 120

= 870

Step2:

LCM(30, 901) = 27030

GCD(30, 901) = ( 30 x 901 ) / 27030

= 30 / 901

= 30

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 870, 120, 901, 756 is 1
