Prime factors of 254 are 2 x 127
Prime factors of 721 are 7 x 103
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 146, 440, 254, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(146, 440) = 32120
GCD(146, 440) = ( 146 x 440 ) / 32120
= 146 / 440
= 146
Step2:
LCM(2, 254) = 254
GCD(2, 254) = ( 2 x 254 ) / 254
= 2 / 254
= 2
Step3:
LCM(2, 721) = 1442
GCD(2, 721) = ( 2 x 721 ) / 1442
= 2 / 721
= 2
So, Greatest Common Divisor of 146, 440, 254, 721 is 1
