Given numbers are 840, 856, 431, 914

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 856 are 2 x 2 x 2 x 107

Prime factors of 431 are 431

Prime factors of 914 are 2 x 457

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

Given numbers are 840, 856, 431, 914

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

Apply this formula for all numbers.

Step1:

LCM(840, 856) = 89880

GCD(840, 856) = ( 840 x 856 ) / 89880

= 840 / 856

= 840

Step2:

LCM(8, 431) = 3448

GCD(8, 431) = ( 8 x 431 ) / 3448

= 8 / 431

= 8

Step3:

LCM(1, 914) = 914

GCD(1, 914) = ( 1 x 914 ) / 914

= 1 / 914

= 1

So, Greatest Common Divisor of 840, 856, 431, 914 is 1
