Steps to Calculate GCD of 385, 645, 309, 148 using LCM Formula
Given numbers are 385, 645, 309, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 645) = 49665
GCD(385, 645) = ( 385 x 645 ) / 49665
= 385 / 645
= 385
Step2:
LCM(5, 309) = 1545
GCD(5, 309) = ( 5 x 309 ) / 1545
= 5 / 309
= 5
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 385, 645, 309, 148 is 1
