Steps to Calculate GCD of 84, 85, 99, 51 using LCM Formula

Given numbers are 84, 85, 99, 51

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

Apply this formula for all numbers.

Step1:

LCM(84, 85) = 7140

GCD(84, 85) = ( 84 x 85 ) / 7140

= 84 / 85

= 84


Step2:

LCM(1, 99) = 99

GCD(1, 99) = ( 1 x 99 ) / 99

= 1 / 99

= 1


Step3:

LCM(1, 51) = 51

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

= 1 / 51

= 1


So, Greatest Common Divisor of 84, 85, 99, 51 is 1
