Steps to Calculate GCD of 945, 239, 121, 305 using LCM Formula
Given numbers are 945, 239, 121, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 239) = 225855
GCD(945, 239) = ( 945 x 239 ) / 225855
= 945 / 239
= 945
Step2:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 945, 239, 121, 305 is 1
