Given numbers are 640, 915, 360, 769

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 915 are 3 x 5 x 61

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 769 are 769

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

Given numbers are 640, 915, 360, 769

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

Apply this formula for all numbers.

Step1:

LCM(640, 915) = 117120

GCD(640, 915) = ( 640 x 915 ) / 117120

= 640 / 915

= 640

Step2:

LCM(5, 360) = 360

GCD(5, 360) = ( 5 x 360 ) / 360

= 5 / 360

= 5

Step3:

LCM(5, 769) = 3845

GCD(5, 769) = ( 5 x 769 ) / 3845

= 5 / 769

= 5

So, Greatest Common Divisor of 640, 915, 360, 769 is 1
