Given numbers are 324, 705, 840, 668

The list of prime factors of all numbers are

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 705 are 3 x 5 x 47

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 324, 705, 840, 668

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

Apply this formula for all numbers.

Step1:

LCM(324, 705) = 76140

GCD(324, 705) = ( 324 x 705 ) / 76140

= 324 / 705

= 324

Step2:

LCM(3, 840) = 840

GCD(3, 840) = ( 3 x 840 ) / 840

= 3 / 840

= 3

Step3:

LCM(3, 668) = 2004

GCD(3, 668) = ( 3 x 668 ) / 2004

= 3 / 668

= 3

So, Greatest Common Divisor of 324, 705, 840, 668 is 1
