Given numbers are 623, 660, 220, 772

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

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

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 623, 660, 220, 772

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

Apply this formula for all numbers.

Step1:

LCM(623, 660) = 411180

GCD(623, 660) = ( 623 x 660 ) / 411180

= 623 / 660

= 623

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 623, 660, 220, 772 is 1
