Given numbers are 482, 989, 550, 420

The list of prime factors of all numbers are

Prime factors of 482 are 2 x 241

Prime factors of 989 are 23 x 43

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 482, 989, 550, 420

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

Apply this formula for all numbers.

Step1:

LCM(482, 989) = 476698

GCD(482, 989) = ( 482 x 989 ) / 476698

= 482 / 989

= 482

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 482, 989, 550, 420 is 1
