Prime factors of 721 are 7 x 103
Prime factors of 565 are 5 x 113
Prime factors of 523 are 523
Prime factors of 254 are 2 x 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 721, 565, 523, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 565) = 407365
GCD(721, 565) = ( 721 x 565 ) / 407365
= 721 / 565
= 721
Step2:
LCM(1, 523) = 523
GCD(1, 523) = ( 1 x 523 ) / 523
= 1 / 523
= 1
Step3:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
So, Greatest Common Divisor of 721, 565, 523, 254 is 1
