Given numbers are 745, 195, 731, 870

The list of prime factors of all numbers are

Prime factors of 745 are 5 x 149

Prime factors of 195 are 3 x 5 x 13

Prime factors of 731 are 17 x 43

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

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

Given numbers are 745, 195, 731, 870

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

Apply this formula for all numbers.

Step1:

LCM(745, 195) = 29055

GCD(745, 195) = ( 745 x 195 ) / 29055

= 745 / 195

= 745

Step2:

LCM(5, 731) = 3655

GCD(5, 731) = ( 5 x 731 ) / 3655

= 5 / 731

= 5

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 745, 195, 731, 870 is 1
