Steps to Calculate GCD of 86, 62, 20, 45 using LCM Formula
Given numbers are 86, 62, 20, 45
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(86, 62) = 2666
GCD(86, 62) = ( 86 x 62 ) / 2666
= 86 / 62
= 86
Step2:
LCM(2, 20) = 20
GCD(2, 20) = ( 2 x 20 ) / 20
= 2 / 20
= 2
Step3:
LCM(2, 45) = 90
GCD(2, 45) = ( 2 x 45 ) / 90
= 2 / 45
= 2
So, Greatest Common Divisor of 86, 62, 20, 45 is 1
