Given numbers are 651, 413, 990, 497

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 413 are 7 x 59

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 497 are 7 x 71

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

Given numbers are 651, 413, 990, 497

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

Apply this formula for all numbers.

Step1:

LCM(651, 413) = 38409

GCD(651, 413) = ( 651 x 413 ) / 38409

= 651 / 413

= 651

Step2:

LCM(7, 990) = 6930

GCD(7, 990) = ( 7 x 990 ) / 6930

= 7 / 990

= 7

Step3:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

So, Greatest Common Divisor of 651, 413, 990, 497 is 1
