Given numbers are 979, 546, 434, 255

The list of prime factors of all numbers are

Prime factors of 979 are 11 x 89

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 434 are 2 x 7 x 31

Prime factors of 255 are 3 x 5 x 17

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

Given numbers are 979, 546, 434, 255

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

Apply this formula for all numbers.

Step1:

LCM(979, 546) = 534534

GCD(979, 546) = ( 979 x 546 ) / 534534

= 979 / 546

= 979

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 979, 546, 434, 255 is 1
