Steps to Calculate GCD of 66, 63, 40, 56 using LCM Formula
Given numbers are 66, 63, 40, 56
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(66, 63) = 1386
GCD(66, 63) = ( 66 x 63 ) / 1386
= 66 / 63
= 66
Step2:
LCM(3, 40) = 120
GCD(3, 40) = ( 3 x 40 ) / 120
= 3 / 40
= 3
Step3:
LCM(1, 56) = 56
GCD(1, 56) = ( 1 x 56 ) / 56
= 1 / 56
= 1
So, Greatest Common Divisor of 66, 63, 40, 56 is 1
