Steps to Calculate GCD of 361, 138, 309, 207 using LCM Formula
Given numbers are 361, 138, 309, 207
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 138) = 49818
GCD(361, 138) = ( 361 x 138 ) / 49818
= 361 / 138
= 361
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
So, Greatest Common Divisor of 361, 138, 309, 207 is 1
