Given numbers are 720, 775, 501, 980

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 775 are 5 x 5 x 31

Prime factors of 501 are 3 x 167

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 720, 775, 501, 980

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

Apply this formula for all numbers.

Step1:

LCM(720, 775) = 111600

GCD(720, 775) = ( 720 x 775 ) / 111600

= 720 / 775

= 720

Step2:

LCM(5, 501) = 2505

GCD(5, 501) = ( 5 x 501 ) / 2505

= 5 / 501

= 5

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 720, 775, 501, 980 is 1
