Given numbers are 660, 124, 561, 463

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 124 are 2 x 2 x 31

Prime factors of 561 are 3 x 11 x 17

Prime factors of 463 are 463

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

Given numbers are 660, 124, 561, 463

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

Apply this formula for all numbers.

Step1:

LCM(660, 124) = 20460

GCD(660, 124) = ( 660 x 124 ) / 20460

= 660 / 124

= 660

Step2:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

Step3:

LCM(1, 463) = 463

GCD(1, 463) = ( 1 x 463 ) / 463

= 1 / 463

= 1

So, Greatest Common Divisor of 660, 124, 561, 463 is 1
