Given numbers are 285, 998, 147, 960

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 998 are 2 x 499

Prime factors of 147 are 3 x 7 x 7

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 285, 998, 147, 960

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

Apply this formula for all numbers.

Step1:

LCM(285, 998) = 284430

GCD(285, 998) = ( 285 x 998 ) / 284430

= 285 / 998

= 285

Step2:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

Step3:

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

= 1 / 960

= 1

So, Greatest Common Divisor of 285, 998, 147, 960 is 1
