Given numbers are 840, 392, 454, 437

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 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 454 are 2 x 227

Prime factors of 437 are 19 x 23

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

Given numbers are 840, 392, 454, 437

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

Apply this formula for all numbers.

Step1:

LCM(840, 392) = 5880

GCD(840, 392) = ( 840 x 392 ) / 5880

= 840 / 392

= 840

Step2:

LCM(56, 454) = 12712

GCD(56, 454) = ( 56 x 454 ) / 12712

= 56 / 454

= 56

Step3:

LCM(2, 437) = 874

GCD(2, 437) = ( 2 x 437 ) / 874

= 2 / 437

= 2

So, Greatest Common Divisor of 840, 392, 454, 437 is 1
