Given numbers are 217, 403, 147, 447

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 403 are 13 x 31

Prime factors of 147 are 3 x 7 x 7

Prime factors of 447 are 3 x 149

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

Given numbers are 217, 403, 147, 447

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

Apply this formula for all numbers.

Step1:

LCM(217, 403) = 2821

GCD(217, 403) = ( 217 x 403 ) / 2821

= 217 / 403

= 217

Step2:

LCM(31, 147) = 4557

GCD(31, 147) = ( 31 x 147 ) / 4557

= 31 / 147

= 31

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 217, 403, 147, 447 is 1
