Given numbers are 643, 104, 980, 276

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 104 are 2 x 2 x 2 x 13

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

Prime factors of 276 are 2 x 2 x 3 x 23

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

Given numbers are 643, 104, 980, 276

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

Apply this formula for all numbers.

Step1:

LCM(643, 104) = 66872

GCD(643, 104) = ( 643 x 104 ) / 66872

= 643 / 104

= 643

Step2:

LCM(1, 980) = 980

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

= 1 / 980

= 1

Step3:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

So, Greatest Common Divisor of 643, 104, 980, 276 is 1
