Given numbers are 660, 755, 731, 721

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 755 are 5 x 151

Prime factors of 731 are 17 x 43

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 660, 755, 731, 721

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

Apply this formula for all numbers.

Step1:

LCM(660, 755) = 99660

GCD(660, 755) = ( 660 x 755 ) / 99660

= 660 / 755

= 660

Step2:

LCM(5, 731) = 3655

GCD(5, 731) = ( 5 x 731 ) / 3655

= 5 / 731

= 5

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 660, 755, 731, 721 is 1
