Given numbers are 403, 212, 218, 990

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 212 are 2 x 2 x 53

Prime factors of 218 are 2 x 109

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

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

Given numbers are 403, 212, 218, 990

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

Apply this formula for all numbers.

Step1:

LCM(403, 212) = 85436

GCD(403, 212) = ( 403 x 212 ) / 85436

= 403 / 212

= 403

Step2:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 403, 212, 218, 990 is 1
