Given numbers are 221, 721, 230, 712
The list of prime factors of all numbers are
Prime factors of 221 are 13 x 17
Prime factors of 721 are 7 x 103
Prime factors of 230 are 2 x 5 x 23
Prime factors of 712 are 2 x 2 x 2 x 89
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 221, 721, 230, 712
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 721) = 159341
GCD(221, 721) = ( 221 x 721 ) / 159341
= 221 / 721
= 221
Step2:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
Step3:
LCM(1, 712) = 712
GCD(1, 712) = ( 1 x 712 ) / 712
= 1 / 712
= 1
So, Greatest Common Divisor of 221, 721, 230, 712 is 1
