Given numbers are 830, 640, 307

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

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

Prime factors of 307 are 307

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

Given numbers are 830, 640, 307

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

Apply this formula for all numbers.

Step1:

LCM(830, 640) = 53120

GCD(830, 640) = ( 830 x 640 ) / 53120

= 830 / 640

= 830

Step2:

LCM(10, 307) = 3070

GCD(10, 307) = ( 10 x 307 ) / 3070

= 10 / 307

= 10

So, Greatest Common Divisor of 830, 640, 307 is 1
