Given numbers are 990, 225, 658, 551

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 225 are 3 x 3 x 5 x 5

Prime factors of 658 are 2 x 7 x 47

Prime factors of 551 are 19 x 29

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

Given numbers are 990, 225, 658, 551

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

Apply this formula for all numbers.

Step1:

LCM(990, 225) = 4950

GCD(990, 225) = ( 990 x 225 ) / 4950

= 990 / 225

= 990

Step2:

LCM(45, 658) = 29610

GCD(45, 658) = ( 45 x 658 ) / 29610

= 45 / 658

= 45

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 990, 225, 658, 551 is 1
