Given numbers are 840, 604, 812, 871

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 604 are 2 x 2 x 151

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 871 are 13 x 67

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

Given numbers are 840, 604, 812, 871

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

Apply this formula for all numbers.

Step1:

LCM(840, 604) = 126840

GCD(840, 604) = ( 840 x 604 ) / 126840

= 840 / 604

= 840

Step2:

LCM(4, 812) = 812

GCD(4, 812) = ( 4 x 812 ) / 812

= 4 / 812

= 4

Step3:

LCM(4, 871) = 3484

GCD(4, 871) = ( 4 x 871 ) / 3484

= 4 / 871

= 4

So, Greatest Common Divisor of 840, 604, 812, 871 is 1
