Given numbers are 497, 840, 396, 641

The list of prime factors of all numbers are

Prime factors of 497 are 7 x 71

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

Prime factors of 641 are 641

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

Given numbers are 497, 840, 396, 641

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

Apply this formula for all numbers.

Step1:

LCM(497, 840) = 59640

GCD(497, 840) = ( 497 x 840 ) / 59640

= 497 / 840

= 497

Step2:

LCM(7, 396) = 2772

GCD(7, 396) = ( 7 x 396 ) / 2772

= 7 / 396

= 7

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 497, 840, 396, 641 is 1
