Given numbers are 668, 660, 124, 261

The list of prime factors of all numbers are

Prime factors of 668 are 2 x 2 x 167

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 261 are 3 x 3 x 29

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

Given numbers are 668, 660, 124, 261

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

Apply this formula for all numbers.

Step1:

LCM(668, 660) = 110220

GCD(668, 660) = ( 668 x 660 ) / 110220

= 668 / 660

= 668

Step2:

LCM(4, 124) = 124

GCD(4, 124) = ( 4 x 124 ) / 124

= 4 / 124

= 4

Step3:

LCM(4, 261) = 1044

GCD(4, 261) = ( 4 x 261 ) / 1044

= 4 / 261

= 4

So, Greatest Common Divisor of 668, 660, 124, 261 is 1
