Steps to Calculate GCD of 35, 27, 15, 78 using LCM Formula
Given numbers are 35, 27, 15, 78
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(35, 27) = 945
GCD(35, 27) = ( 35 x 27 ) / 945
= 35 / 27
= 35
Step2:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
Step3:
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
= 1 / 78
= 1
So, Greatest Common Divisor of 35, 27, 15, 78 is 1
