Given numbers are 215, 656, 251, 249
The list of prime factors of all numbers are
Prime factors of 215 are 5 x 43
Prime factors of 656 are 2 x 2 x 2 x 2 x 41
Prime factors of 251 are 251
Prime factors of 249 are 3 x 83
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 215, 656, 251, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 656) = 141040
GCD(215, 656) = ( 215 x 656 ) / 141040
= 215 / 656
= 215
Step2:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 215, 656, 251, 249 is 1
