Given numbers are 840, 468, 815, 947

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 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 815 are 5 x 163

Prime factors of 947 are 947

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

Given numbers are 840, 468, 815, 947

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

Apply this formula for all numbers.

Step1:

LCM(840, 468) = 32760

GCD(840, 468) = ( 840 x 468 ) / 32760

= 840 / 468

= 840

Step2:

LCM(12, 815) = 9780

GCD(12, 815) = ( 12 x 815 ) / 9780

= 12 / 815

= 12

Step3:

LCM(1, 947) = 947

GCD(1, 947) = ( 1 x 947 ) / 947

= 1 / 947

= 1

So, Greatest Common Divisor of 840, 468, 815, 947 is 1
