Given numbers are 840, 238, 949, 129

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 238 are 2 x 7 x 17

Prime factors of 949 are 13 x 73

Prime factors of 129 are 3 x 43

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

Given numbers are 840, 238, 949, 129

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

Apply this formula for all numbers.

Step1:

LCM(840, 238) = 14280

GCD(840, 238) = ( 840 x 238 ) / 14280

= 840 / 238

= 840

Step2:

LCM(14, 949) = 13286

GCD(14, 949) = ( 14 x 949 ) / 13286

= 14 / 949

= 14

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 840, 238, 949, 129 is 1
