Given numbers are 965, 870, 390, 648

The list of prime factors of all numbers are

Prime factors of 965 are 5 x 193

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 965, 870, 390, 648

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

Apply this formula for all numbers.

Step1:

LCM(965, 870) = 167910

GCD(965, 870) = ( 965 x 870 ) / 167910

= 965 / 870

= 965

Step2:

LCM(5, 390) = 390

GCD(5, 390) = ( 5 x 390 ) / 390

= 5 / 390

= 5

Step3:

LCM(5, 648) = 3240

GCD(5, 648) = ( 5 x 648 ) / 3240

= 5 / 648

= 5

So, Greatest Common Divisor of 965, 870, 390, 648 is 1
