Given numbers are 126, 102, 280, 643

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 102 are 2 x 3 x 17

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 643 are 643

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

Given numbers are 126, 102, 280, 643

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

Apply this formula for all numbers.

Step1:

LCM(126, 102) = 2142

GCD(126, 102) = ( 126 x 102 ) / 2142

= 126 / 102

= 126

Step2:

LCM(6, 280) = 840

GCD(6, 280) = ( 6 x 280 ) / 840

= 6 / 280

= 6

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 126, 102, 280, 643 is 1
