Steps to Calculate GCD of 78, 30, 83, 51 using LCM Formula

Given numbers are 78, 30, 83, 51

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

Apply this formula for all numbers.

Step1:

LCM(78, 30) = 390

GCD(78, 30) = ( 78 x 30 ) / 390

= 78 / 30

= 78


Step2:

LCM(6, 83) = 498

GCD(6, 83) = ( 6 x 83 ) / 498

= 6 / 83

= 6


Step3:

LCM(1, 51) = 51

GCD(1, 51) = ( 1 x 51 ) / 51

= 1 / 51

= 1


So, Greatest Common Divisor of 78, 30, 83, 51 is 1
