Given numbers are 789, 222, 840, 875

The list of prime factors of all numbers are

Prime factors of 789 are 3 x 263

Prime factors of 222 are 2 x 3 x 37

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

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

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

Given numbers are 789, 222, 840, 875

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

Apply this formula for all numbers.

Step1:

LCM(789, 222) = 58386

GCD(789, 222) = ( 789 x 222 ) / 58386

= 789 / 222

= 789

Step2:

LCM(3, 840) = 840

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

= 3 / 840

= 3

Step3:

LCM(3, 875) = 2625

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

= 3 / 875

= 3

So, Greatest Common Divisor of 789, 222, 840, 875 is 1
