Given numbers are 662, 663, 763, 720

The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

Prime factors of 663 are 3 x 13 x 17

Prime factors of 763 are 7 x 109

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 662, 663, 763, 720

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

Apply this formula for all numbers.

Step1:

LCM(662, 663) = 438906

GCD(662, 663) = ( 662 x 663 ) / 438906

= 662 / 663

= 662

Step2:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 662, 663, 763, 720 is 1
