Given numbers are 780, 612, 320, 707

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 707 are 7 x 101

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

Given numbers are 780, 612, 320, 707

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

Apply this formula for all numbers.

Step1:

LCM(780, 612) = 39780

GCD(780, 612) = ( 780 x 612 ) / 39780

= 780 / 612

= 780

Step2:

LCM(12, 320) = 960

GCD(12, 320) = ( 12 x 320 ) / 960

= 12 / 320

= 12

Step3:

LCM(4, 707) = 2828

GCD(4, 707) = ( 4 x 707 ) / 2828

= 4 / 707

= 4

So, Greatest Common Divisor of 780, 612, 320, 707 is 1
