Given numbers are 819, 870, 959, 942

The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

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

Prime factors of 959 are 7 x 137

Prime factors of 942 are 2 x 3 x 157

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

Given numbers are 819, 870, 959, 942

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

Apply this formula for all numbers.

Step1:

LCM(819, 870) = 237510

GCD(819, 870) = ( 819 x 870 ) / 237510

= 819 / 870

= 819

Step2:

LCM(3, 959) = 2877

GCD(3, 959) = ( 3 x 959 ) / 2877

= 3 / 959

= 3

Step3:

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

= 1 / 942

= 1

So, Greatest Common Divisor of 819, 870, 959, 942 is 1
