Given numbers are 415, 311, 221, 626
The list of prime factors of all numbers are
Prime factors of 415 are 5 x 83
Prime factors of 311 are 311
Prime factors of 221 are 13 x 17
Prime factors of 626 are 2 x 313
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 415, 311, 221, 626
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 311) = 129065
GCD(415, 311) = ( 415 x 311 ) / 129065
= 415 / 311
= 415
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 626) = 626
GCD(1, 626) = ( 1 x 626 ) / 626
= 1 / 626
= 1
So, Greatest Common Divisor of 415, 311, 221, 626 is 1
