Given numbers are 455, 245, 155, 226
The list of prime factors of all numbers are
Prime factors of 455 are 5 x 7 x 13
Prime factors of 245 are 5 x 7 x 7
Prime factors of 155 are 5 x 31
Prime factors of 226 are 2 x 113
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 455, 245, 155, 226
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(455, 245) = 3185
GCD(455, 245) = ( 455 x 245 ) / 3185
= 455 / 245
= 455
Step2:
LCM(35, 155) = 1085
GCD(35, 155) = ( 35 x 155 ) / 1085
= 35 / 155
= 35
Step3:
LCM(5, 226) = 1130
GCD(5, 226) = ( 5 x 226 ) / 1130
= 5 / 226
= 5
So, Greatest Common Divisor of 455, 245, 155, 226 is 1
