Given numbers are 100, 224, 447, 390

The list of prime factors of all numbers are

Prime factors of 100 are 2 x 2 x 5 x 5

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

Prime factors of 447 are 3 x 149

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 100, 224, 447, 390

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

Apply this formula for all numbers.

Step1:

LCM(100, 224) = 5600

GCD(100, 224) = ( 100 x 224 ) / 5600

= 100 / 224

= 100

Step2:

LCM(4, 447) = 1788

GCD(4, 447) = ( 4 x 447 ) / 1788

= 4 / 447

= 4

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 100, 224, 447, 390 is 1
