Given numbers are 660, 781, 608, 268

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 781 are 11 x 71

Prime factors of 608 are 2 x 2 x 2 x 2 x 2 x 19

Prime factors of 268 are 2 x 2 x 67

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

Given numbers are 660, 781, 608, 268

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

Apply this formula for all numbers.

Step1:

LCM(660, 781) = 46860

GCD(660, 781) = ( 660 x 781 ) / 46860

= 660 / 781

= 660

Step2:

LCM(11, 608) = 6688

GCD(11, 608) = ( 11 x 608 ) / 6688

= 11 / 608

= 11

Step3:

LCM(1, 268) = 268

GCD(1, 268) = ( 1 x 268 ) / 268

= 1 / 268

= 1

So, Greatest Common Divisor of 660, 781, 608, 268 is 1
