Steps to Calculate GCD of 840, 518, 71, 100 using LCM Formula

Given numbers are 840, 518, 71, 100

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

Apply this formula for all numbers.

Step1:

LCM(840, 518) = 31080

GCD(840, 518) = ( 840 x 518 ) / 31080

= 840 / 518

= 840


Step2:

LCM(14, 71) = 994

GCD(14, 71) = ( 14 x 71 ) / 994

= 14 / 71

= 14


Step3:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1


So, Greatest Common Divisor of 840, 518, 71, 100 is 1
