Given numbers are 720, 548, 817, 647

The list of prime factors of all numbers are

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

Prime factors of 548 are 2 x 2 x 137

Prime factors of 817 are 19 x 43

Prime factors of 647 are 647

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

Given numbers are 720, 548, 817, 647

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

Apply this formula for all numbers.

Step1:

LCM(720, 548) = 98640

GCD(720, 548) = ( 720 x 548 ) / 98640

= 720 / 548

= 720

Step2:

LCM(4, 817) = 3268

GCD(4, 817) = ( 4 x 817 ) / 3268

= 4 / 817

= 4

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 720, 548, 817, 647 is 1
