Steps to Calculate GCD of 789, 395, 445, 221 using LCM Formula
Given numbers are 789, 395, 445, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 395) = 311655
GCD(789, 395) = ( 789 x 395 ) / 311655
= 789 / 395
= 789
Step2:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 789, 395, 445, 221 is 1
