Steps to Calculate GCD of 195, 309, 778, 609 using LCM Formula
Given numbers are 195, 309, 778, 609
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(195, 309) = 20085
GCD(195, 309) = ( 195 x 309 ) / 20085
= 195 / 309
= 195
Step2:
LCM(3, 778) = 2334
GCD(3, 778) = ( 3 x 778 ) / 2334
= 3 / 778
= 3
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 195, 309, 778, 609 is 1
