The list of prime factors of all numbers are
Prime factors of 223 are 223
Prime factors of 442 are 2 x 13 x 17
Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime factors of 451 are 11 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 223, 442, 256, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(223, 442) = 98566
GCD(223, 442) = ( 223 x 442 ) / 98566
= 223 / 442
= 223
Step2:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
Step3:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
So, Greatest Common Divisor of 223, 442, 256, 451 is 1
