Given numbers are 980, 144, 113, 644

The list of prime factors of all numbers are

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 113 are 113

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 980, 144, 113, 644

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

Apply this formula for all numbers.

Step1:

LCM(980, 144) = 35280

GCD(980, 144) = ( 980 x 144 ) / 35280

= 980 / 144

= 980

Step2:

LCM(4, 113) = 452

GCD(4, 113) = ( 4 x 113 ) / 452

= 4 / 113

= 4

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 980, 144, 113, 644 is 1
