Steps to Calculate GCD of 102, 730, 155, 309 using LCM Formula
Given numbers are 102, 730, 155, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 730) = 37230
GCD(102, 730) = ( 102 x 730 ) / 37230
= 102 / 730
= 102
Step2:
LCM(2, 155) = 310
GCD(2, 155) = ( 2 x 155 ) / 310
= 2 / 155
= 2
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 102, 730, 155, 309 is 1
