Given numbers are 680, 644, 477, 202

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 477 are 3 x 3 x 53

Prime factors of 202 are 2 x 101

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

Given numbers are 680, 644, 477, 202

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

Apply this formula for all numbers.

Step1:

LCM(680, 644) = 109480

GCD(680, 644) = ( 680 x 644 ) / 109480

= 680 / 644

= 680

Step2:

LCM(4, 477) = 1908

GCD(4, 477) = ( 4 x 477 ) / 1908

= 4 / 477

= 4

Step3:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

So, Greatest Common Divisor of 680, 644, 477, 202 is 1
