Given numbers are 497, 680, 118, 840

The list of prime factors of all numbers are

Prime factors of 497 are 7 x 71

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 118 are 2 x 59

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

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

Given numbers are 497, 680, 118, 840

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

Apply this formula for all numbers.

Step1:

LCM(497, 680) = 337960

GCD(497, 680) = ( 497 x 680 ) / 337960

= 497 / 680

= 497

Step2:

LCM(1, 118) = 118

GCD(1, 118) = ( 1 x 118 ) / 118

= 1 / 118

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 497, 680, 118, 840 is 1
