Given numbers are 695, 777, 456, 640

The list of prime factors of all numbers are

Prime factors of 695 are 5 x 139

Prime factors of 777 are 3 x 7 x 37

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 695, 777, 456, 640

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

Apply this formula for all numbers.

Step1:

LCM(695, 777) = 540015

GCD(695, 777) = ( 695 x 777 ) / 540015

= 695 / 777

= 695

Step2:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 695, 777, 456, 640 is 1
