Steps to Calculate GCD of 309, 145, 545, 193 using LCM Formula
Given numbers are 309, 145, 545, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 145) = 44805
GCD(309, 145) = ( 309 x 145 ) / 44805
= 309 / 145
= 309
Step2:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 309, 145, 545, 193 is 1
