Given numbers are 485, 255, 148, 221
The list of prime factors of all numbers are
Prime factors of 485 are 5 x 97
Prime factors of 255 are 3 x 5 x 17
Prime factors of 148 are 2 x 2 x 37
Prime factors of 221 are 13 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 485, 255, 148, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(485, 255) = 24735
GCD(485, 255) = ( 485 x 255 ) / 24735
= 485 / 255
= 485
Step2:
LCM(5, 148) = 740
GCD(5, 148) = ( 5 x 148 ) / 740
= 5 / 148
= 5
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 485, 255, 148, 221 is 1
