Given numbers are 980, 992, 421, 145

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 992 are 2 x 2 x 2 x 2 x 2 x 31

Prime factors of 421 are 421

Prime factors of 145 are 5 x 29

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

Given numbers are 980, 992, 421, 145

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

Apply this formula for all numbers.

Step1:

LCM(980, 992) = 243040

GCD(980, 992) = ( 980 x 992 ) / 243040

= 980 / 992

= 980

Step2:

LCM(4, 421) = 1684

GCD(4, 421) = ( 4 x 421 ) / 1684

= 4 / 421

= 4

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 980, 992, 421, 145 is 1
