Given numbers are 833, 870, 689, 420

The list of prime factors of all numbers are

Prime factors of 833 are 7 x 7 x 17

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 689 are 13 x 53

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 833, 870, 689, 420

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

Apply this formula for all numbers.

Step1:

LCM(833, 870) = 724710

GCD(833, 870) = ( 833 x 870 ) / 724710

= 833 / 870

= 833

Step2:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 833, 870, 689, 420 is 1
