Given numbers are 915, 190, 760, 644

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 190 are 2 x 5 x 19

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 915, 190, 760, 644

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

Apply this formula for all numbers.

Step1:

LCM(915, 190) = 34770

GCD(915, 190) = ( 915 x 190 ) / 34770

= 915 / 190

= 915

Step2:

LCM(5, 760) = 760

GCD(5, 760) = ( 5 x 760 ) / 760

= 5 / 760

= 5

Step3:

LCM(5, 644) = 3220

GCD(5, 644) = ( 5 x 644 ) / 3220

= 5 / 644

= 5

So, Greatest Common Divisor of 915, 190, 760, 644 is 1
