Given numbers are 749, 681, 880, 646

The list of prime factors of all numbers are

Prime factors of 749 are 7 x 107

Prime factors of 681 are 3 x 227

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 749, 681, 880, 646

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

Apply this formula for all numbers.

Step1:

LCM(749, 681) = 510069

GCD(749, 681) = ( 749 x 681 ) / 510069

= 749 / 681

= 749

Step2:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 749, 681, 880, 646 is 1
