Given numbers are 655, 134, 684, 685

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 134 are 2 x 67

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 685 are 5 x 137

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

Given numbers are 655, 134, 684, 685

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

Apply this formula for all numbers.

Step1:

LCM(655, 134) = 87770

GCD(655, 134) = ( 655 x 134 ) / 87770

= 655 / 134

= 655

Step2:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 655, 134, 684, 685 is 1
