Given numbers are 870, 860, 731, 611

The list of prime factors of all numbers are

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

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 731 are 17 x 43

Prime factors of 611 are 13 x 47

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

Given numbers are 870, 860, 731, 611

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

Apply this formula for all numbers.

Step1:

LCM(870, 860) = 74820

GCD(870, 860) = ( 870 x 860 ) / 74820

= 870 / 860

= 870

Step2:

LCM(10, 731) = 7310

GCD(10, 731) = ( 10 x 731 ) / 7310

= 10 / 731

= 10

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 870, 860, 731, 611 is 1
