Steps to Calculate GCD of 23, 40, 87, 86 using LCM Formula
Given numbers are 23, 40, 87, 86
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(23, 40) = 920
GCD(23, 40) = ( 23 x 40 ) / 920
= 23 / 40
= 23
Step2:
LCM(1, 87) = 87
GCD(1, 87) = ( 1 x 87 ) / 87
= 1 / 87
= 1
Step3:
LCM(1, 86) = 86
GCD(1, 86) = ( 1 x 86 ) / 86
= 1 / 86
= 1
So, Greatest Common Divisor of 23, 40, 87, 86 is 1
