Given numbers are 223, 147, 432, 781

The list of prime factors of all numbers are

Prime factors of 223 are 223

Prime factors of 147 are 3 x 7 x 7

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 781 are 11 x 71

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

Given numbers are 223, 147, 432, 781

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

Apply this formula for all numbers.

Step1:

LCM(223, 147) = 32781

GCD(223, 147) = ( 223 x 147 ) / 32781

= 223 / 147

= 223

Step2:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 223, 147, 432, 781 is 1
