Given numbers are 658, 861, 984, 108

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 861 are 3 x 7 x 41

Prime factors of 984 are 2 x 2 x 2 x 3 x 41

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 658, 861, 984, 108

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

Apply this formula for all numbers.

Step1:

LCM(658, 861) = 80934

GCD(658, 861) = ( 658 x 861 ) / 80934

= 658 / 861

= 658

Step2:

LCM(7, 984) = 6888

GCD(7, 984) = ( 7 x 984 ) / 6888

= 7 / 984

= 7

Step3:

LCM(1, 108) = 108

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

= 1 / 108

= 1

So, Greatest Common Divisor of 658, 861, 984, 108 is 1
