Given numbers are 742, 651, 308, 655

The list of prime factors of all numbers are

Prime factors of 742 are 2 x 7 x 53

Prime factors of 651 are 3 x 7 x 31

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 655 are 5 x 131

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

Given numbers are 742, 651, 308, 655

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

Apply this formula for all numbers.

Step1:

LCM(742, 651) = 69006

GCD(742, 651) = ( 742 x 651 ) / 69006

= 742 / 651

= 742

Step2:

LCM(7, 308) = 308

GCD(7, 308) = ( 7 x 308 ) / 308

= 7 / 308

= 7

Step3:

LCM(7, 655) = 4585

GCD(7, 655) = ( 7 x 655 ) / 4585

= 7 / 655

= 7

So, Greatest Common Divisor of 742, 651, 308, 655 is 1
