Steps to Calculate GCD of 417, 171, 65, 115 using LCM Formula
Given numbers are 417, 171, 65, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 171) = 23769
GCD(417, 171) = ( 417 x 171 ) / 23769
= 417 / 171
= 417
Step2:
LCM(3, 65) = 195
GCD(3, 65) = ( 3 x 65 ) / 195
= 3 / 65
= 3
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 417, 171, 65, 115 is 1
