Given numbers are 994, 100, 159, 644

The list of prime factors of all numbers are

Prime factors of 994 are 2 x 7 x 71

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 159 are 3 x 53

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 994, 100, 159, 644

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

Apply this formula for all numbers.

Step1:

LCM(994, 100) = 49700

GCD(994, 100) = ( 994 x 100 ) / 49700

= 994 / 100

= 994

Step2:

LCM(2, 159) = 318

GCD(2, 159) = ( 2 x 159 ) / 318

= 2 / 159

= 2

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 994, 100, 159, 644 is 1
