Given numbers are 678, 130, 978, 121

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 130 are 2 x 5 x 13

Prime factors of 978 are 2 x 3 x 163

Prime factors of 121 are 11 x 11

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

Given numbers are 678, 130, 978, 121

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

Apply this formula for all numbers.

Step1:

LCM(678, 130) = 44070

GCD(678, 130) = ( 678 x 130 ) / 44070

= 678 / 130

= 678

Step2:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

Step3:

LCM(2, 121) = 242

GCD(2, 121) = ( 2 x 121 ) / 242

= 2 / 121

= 2

So, Greatest Common Divisor of 678, 130, 978, 121 is 1
