Steps to Calculate GCD of 840, 305, 506, 744 using LCM Formula

Given numbers are 840, 305, 506, 744

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

Apply this formula for all numbers.

Step1:

LCM(840, 305) = 51240

GCD(840, 305) = ( 840 x 305 ) / 51240

= 840 / 305

= 840


Step2:

LCM(5, 506) = 2530

GCD(5, 506) = ( 5 x 506 ) / 2530

= 5 / 506

= 5


Step3:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1


So, Greatest Common Divisor of 840, 305, 506, 744 is 1
