Given numbers are 840, 213, 325, 242

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 213 are 3 x 71

Prime factors of 325 are 5 x 5 x 13

Prime factors of 242 are 2 x 11 x 11

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

Given numbers are 840, 213, 325, 242

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

Apply this formula for all numbers.

Step1:

LCM(840, 213) = 59640

GCD(840, 213) = ( 840 x 213 ) / 59640

= 840 / 213

= 840

Step2:

LCM(3, 325) = 975

GCD(3, 325) = ( 3 x 325 ) / 975

= 3 / 325

= 3

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 840, 213, 325, 242 is 1
