Given numbers are 766, 721, 242, 720

The list of prime factors of all numbers are

Prime factors of 766 are 2 x 383

Prime factors of 721 are 7 x 103

Prime factors of 242 are 2 x 11 x 11

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 766, 721, 242, 720

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

Apply this formula for all numbers.

Step1:

LCM(766, 721) = 552286

GCD(766, 721) = ( 766 x 721 ) / 552286

= 766 / 721

= 766

Step2:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 766, 721, 242, 720 is 1
