Steps to Calculate GCD of 12, 66, 61, 97 using LCM Formula
Given numbers are 12, 66, 61, 97
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(12, 66) = 132
GCD(12, 66) = ( 12 x 66 ) / 132
= 12 / 66
= 12
Step2:
LCM(6, 61) = 366
GCD(6, 61) = ( 6 x 61 ) / 366
= 6 / 61
= 6
Step3:
LCM(1, 97) = 97
GCD(1, 97) = ( 1 x 97 ) / 97
= 1 / 97
= 1
So, Greatest Common Divisor of 12, 66, 61, 97 is 1
