Given numbers are 990, 478, 846, 147

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 478 are 2 x 239

Prime factors of 846 are 2 x 3 x 3 x 47

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 990, 478, 846, 147

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

Apply this formula for all numbers.

Step1:

LCM(990, 478) = 236610

GCD(990, 478) = ( 990 x 478 ) / 236610

= 990 / 478

= 990

Step2:

LCM(2, 846) = 846

GCD(2, 846) = ( 2 x 846 ) / 846

= 2 / 846

= 2

Step3:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

So, Greatest Common Divisor of 990, 478, 846, 147 is 1
