Given numbers are 618, 748, 757, 721

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 748 are 2 x 2 x 11 x 17

Prime factors of 757 are 757

Prime factors of 721 are 7 x 103

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

Given numbers are 618, 748, 757, 721

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

Apply this formula for all numbers.

Step1:

LCM(618, 748) = 231132

GCD(618, 748) = ( 618 x 748 ) / 231132

= 618 / 748

= 618

Step2:

LCM(2, 757) = 1514

GCD(2, 757) = ( 2 x 757 ) / 1514

= 2 / 757

= 2

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 618, 748, 757, 721 is 1
