Given numbers are 840, 141, 691, 634

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 141 are 3 x 47

Prime factors of 691 are 691

Prime factors of 634 are 2 x 317

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

Given numbers are 840, 141, 691, 634

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

Apply this formula for all numbers.

Step1:

LCM(840, 141) = 39480

GCD(840, 141) = ( 840 x 141 ) / 39480

= 840 / 141

= 840

Step2:

LCM(3, 691) = 2073

GCD(3, 691) = ( 3 x 691 ) / 2073

= 3 / 691

= 3

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 840, 141, 691, 634 is 1
