Given numbers are 840, 872, 505, 702

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 872 are 2 x 2 x 2 x 109

Prime factors of 505 are 5 x 101

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 840, 872, 505, 702

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

Apply this formula for all numbers.

Step1:

LCM(840, 872) = 91560

GCD(840, 872) = ( 840 x 872 ) / 91560

= 840 / 872

= 840

Step2:

LCM(8, 505) = 4040

GCD(8, 505) = ( 8 x 505 ) / 4040

= 8 / 505

= 8

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 840, 872, 505, 702 is 1
