Given numbers are 860, 195, 915, 921

The list of prime factors of all numbers are

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

Prime factors of 195 are 3 x 5 x 13

Prime factors of 915 are 3 x 5 x 61

Prime factors of 921 are 3 x 307

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

Given numbers are 860, 195, 915, 921

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

Apply this formula for all numbers.

Step1:

LCM(860, 195) = 33540

GCD(860, 195) = ( 860 x 195 ) / 33540

= 860 / 195

= 860

Step2:

LCM(5, 915) = 915

GCD(5, 915) = ( 5 x 915 ) / 915

= 5 / 915

= 5

Step3:

LCM(5, 921) = 4605

GCD(5, 921) = ( 5 x 921 ) / 4605

= 5 / 921

= 5

So, Greatest Common Divisor of 860, 195, 915, 921 is 1
