Given numbers are 480, 477, 688, 655

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 477 are 3 x 3 x 53

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 655 are 5 x 131

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

Given numbers are 480, 477, 688, 655

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

Apply this formula for all numbers.

Step1:

LCM(480, 477) = 76320

GCD(480, 477) = ( 480 x 477 ) / 76320

= 480 / 477

= 480

Step2:

LCM(3, 688) = 2064

GCD(3, 688) = ( 3 x 688 ) / 2064

= 3 / 688

= 3

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 480, 477, 688, 655 is 1
