Given numbers are 840, 530, 324, 407

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 530 are 2 x 5 x 53

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

Prime factors of 407 are 11 x 37

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

Given numbers are 840, 530, 324, 407

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

Apply this formula for all numbers.

Step1:

LCM(840, 530) = 44520

GCD(840, 530) = ( 840 x 530 ) / 44520

= 840 / 530

= 840

Step2:

LCM(10, 324) = 1620

GCD(10, 324) = ( 10 x 324 ) / 1620

= 10 / 324

= 10

Step3:

LCM(2, 407) = 814

GCD(2, 407) = ( 2 x 407 ) / 814

= 2 / 407

= 2

So, Greatest Common Divisor of 840, 530, 324, 407 is 1
