Given numbers are 561, 464, 77, 502

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 464 are 2 x 2 x 2 x 2 x 29

Prime factors of 77 are 7 x 11

Prime factors of 502 are 2 x 251

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

Given numbers are 561, 464, 77, 502

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

Apply this formula for all numbers.

Step1:

LCM(561, 464) = 260304

GCD(561, 464) = ( 561 x 464 ) / 260304

= 561 / 464

= 561

Step2:

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

= 1 / 77

= 1

Step3:

LCM(1, 502) = 502

GCD(1, 502) = ( 1 x 502 ) / 502

= 1 / 502

= 1

So, Greatest Common Divisor of 561, 464, 77, 502 is 1
