Given numbers are 651, 247, 123, 355

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 247 are 13 x 19

Prime factors of 123 are 3 x 41

Prime factors of 355 are 5 x 71

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

Given numbers are 651, 247, 123, 355

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

Apply this formula for all numbers.

Step1:

LCM(651, 247) = 160797

GCD(651, 247) = ( 651 x 247 ) / 160797

= 651 / 247

= 651

Step2:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 651, 247, 123, 355 is 1
