Given numbers are 427, 224, 283, 645

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 224 are 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 283 are 283

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 427, 224, 283, 645

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

Apply this formula for all numbers.

Step1:

LCM(427, 224) = 13664

GCD(427, 224) = ( 427 x 224 ) / 13664

= 427 / 224

= 427

Step2:

LCM(7, 283) = 1981

GCD(7, 283) = ( 7 x 283 ) / 1981

= 7 / 283

= 7

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 427, 224, 283, 645 is 1
