Steps to Calculate GCD of 91, 77, 33, 68 using LCM Formula
Given numbers are 91, 77, 33, 68
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(91, 77) = 1001
GCD(91, 77) = ( 91 x 77 ) / 1001
= 91 / 77
= 91
Step2:
LCM(7, 33) = 231
GCD(7, 33) = ( 7 x 33 ) / 231
= 7 / 33
= 7
Step3:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
So, Greatest Common Divisor of 91, 77, 33, 68 is 1
