Given numbers are 840, 669, 875, 401

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 669 are 3 x 223

Prime factors of 875 are 5 x 5 x 5 x 7

Prime factors of 401 are 401

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

Given numbers are 840, 669, 875, 401

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

Apply this formula for all numbers.

Step1:

LCM(840, 669) = 187320

GCD(840, 669) = ( 840 x 669 ) / 187320

= 840 / 669

= 840

Step2:

LCM(3, 875) = 2625

GCD(3, 875) = ( 3 x 875 ) / 2625

= 3 / 875

= 3

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 840, 669, 875, 401 is 1
