Steps to Calculate GCD of 50, 85, 78, 61 using LCM Formula
Given numbers are 50, 85, 78, 61
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(50, 85) = 850
GCD(50, 85) = ( 50 x 85 ) / 850
= 50 / 85
= 50
Step2:
LCM(5, 78) = 390
GCD(5, 78) = ( 5 x 78 ) / 390
= 5 / 78
= 5
Step3:
LCM(1, 61) = 61
GCD(1, 61) = ( 1 x 61 ) / 61
= 1 / 61
= 1
So, Greatest Common Divisor of 50, 85, 78, 61 is 1
