Given numbers are 655, 807, 860, 684

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 807 are 3 x 269

Prime factors of 860 are 2 x 2 x 5 x 43

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

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

Given numbers are 655, 807, 860, 684

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

Apply this formula for all numbers.

Step1:

LCM(655, 807) = 528585

GCD(655, 807) = ( 655 x 807 ) / 528585

= 655 / 807

= 655

Step2:

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

= 1 / 860

= 1

Step3:

LCM(1, 684) = 684

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

= 1 / 684

= 1

So, Greatest Common Divisor of 655, 807, 860, 684 is 1
