Given numbers are 623, 685, 860, 108

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 685 are 5 x 137

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

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

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

Given numbers are 623, 685, 860, 108

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

Apply this formula for all numbers.

Step1:

LCM(623, 685) = 426755

GCD(623, 685) = ( 623 x 685 ) / 426755

= 623 / 685

= 623

Step2:

LCM(1, 860) = 860

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

= 1 / 860

= 1

Step3:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 623, 685, 860, 108 is 1
