Given numbers are 840, 882, 315, 680

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 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 840, 882, 315, 680

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

Apply this formula for all numbers.

Step1:

LCM(840, 882) = 17640

GCD(840, 882) = ( 840 x 882 ) / 17640

= 840 / 882

= 840

Step2:

LCM(42, 315) = 630

GCD(42, 315) = ( 42 x 315 ) / 630

= 42 / 315

= 42

Step3:

LCM(21, 680) = 14280

GCD(21, 680) = ( 21 x 680 ) / 14280

= 21 / 680

= 21

So, Greatest Common Divisor of 840, 882, 315, 680 is 1
