Steps to Calculate GCD of 95, 20, 91, 66 using LCM Formula
Given numbers are 95, 20, 91, 66
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(95, 20) = 380
GCD(95, 20) = ( 95 x 20 ) / 380
= 95 / 20
= 95
Step2:
LCM(5, 91) = 455
GCD(5, 91) = ( 5 x 91 ) / 455
= 5 / 91
= 5
Step3:
LCM(1, 66) = 66
GCD(1, 66) = ( 1 x 66 ) / 66
= 1 / 66
= 1
So, Greatest Common Divisor of 95, 20, 91, 66 is 1
