Given numbers are 840, 680, 634, 435

The list of prime factors of all numbers are

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

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

Prime factors of 634 are 2 x 317

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 840, 680, 634, 435

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

Apply this formula for all numbers.

Step1:

LCM(840, 680) = 14280

GCD(840, 680) = ( 840 x 680 ) / 14280

= 840 / 680

= 840

Step2:

LCM(40, 634) = 12680

GCD(40, 634) = ( 40 x 634 ) / 12680

= 40 / 634

= 40

Step3:

LCM(2, 435) = 870

GCD(2, 435) = ( 2 x 435 ) / 870

= 2 / 435

= 2

So, Greatest Common Divisor of 840, 680, 634, 435 is 1
