Given numbers are 980, 838, 129, 147

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 838 are 2 x 419

Prime factors of 129 are 3 x 43

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 980, 838, 129, 147

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

Apply this formula for all numbers.

Step1:

LCM(980, 838) = 410620

GCD(980, 838) = ( 980 x 838 ) / 410620

= 980 / 838

= 980

Step2:

LCM(2, 129) = 258

GCD(2, 129) = ( 2 x 129 ) / 258

= 2 / 129

= 2

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 980, 838, 129, 147 is 1
