Given numbers are 915, 670, 999, 784

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 670 are 2 x 5 x 67

Prime factors of 999 are 3 x 3 x 3 x 37

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 915, 670, 999, 784

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

Apply this formula for all numbers.

Step1:

LCM(915, 670) = 122610

GCD(915, 670) = ( 915 x 670 ) / 122610

= 915 / 670

= 915

Step2:

LCM(5, 999) = 4995

GCD(5, 999) = ( 5 x 999 ) / 4995

= 5 / 999

= 5

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 915, 670, 999, 784 is 1
