Given numbers are 946, 780, 695, 642

The list of prime factors of all numbers are

Prime factors of 946 are 2 x 11 x 43

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

Prime factors of 695 are 5 x 139

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 946, 780, 695, 642

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

Apply this formula for all numbers.

Step1:

LCM(946, 780) = 368940

GCD(946, 780) = ( 946 x 780 ) / 368940

= 946 / 780

= 946

Step2:

LCM(2, 695) = 1390

GCD(2, 695) = ( 2 x 695 ) / 1390

= 2 / 695

= 2

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 946, 780, 695, 642 is 1
