Given numbers are 647, 715, 614, 980

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 715 are 5 x 11 x 13

Prime factors of 614 are 2 x 307

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 647, 715, 614, 980

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

Apply this formula for all numbers.

Step1:

LCM(647, 715) = 462605

GCD(647, 715) = ( 647 x 715 ) / 462605

= 647 / 715

= 647

Step2:

LCM(1, 614) = 614

GCD(1, 614) = ( 1 x 614 ) / 614

= 1 / 614

= 1

Step3:

LCM(1, 980) = 980

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

= 1 / 980

= 1

So, Greatest Common Divisor of 647, 715, 614, 980 is 1
