Steps to Calculate GCD of 92, 86, 78, 21 using LCM Formula

Given numbers are 92, 86, 78, 21

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(92, 86) = 3956

GCD(92, 86) = ( 92 x 86 ) / 3956

= 92 / 86

= 92


Step2:

LCM(2, 78) = 78

GCD(2, 78) = ( 2 x 78 ) / 78

= 2 / 78

= 2


Step3:

LCM(2, 21) = 42

GCD(2, 21) = ( 2 x 21 ) / 42

= 2 / 21

= 2


So, Greatest Common Divisor of 92, 86, 78, 21 is 1
