Given numbers are 406, 958, 641, 980

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 958 are 2 x 479

Prime factors of 641 are 641

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

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

Given numbers are 406, 958, 641, 980

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

Apply this formula for all numbers.

Step1:

LCM(406, 958) = 194474

GCD(406, 958) = ( 406 x 958 ) / 194474

= 406 / 958

= 406

Step2:

LCM(2, 641) = 1282

GCD(2, 641) = ( 2 x 641 ) / 1282

= 2 / 641

= 2

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 406, 958, 641, 980 is 1
