Therefore, GCD of 840, 780, 740, 918 is 2.

Given numbers are 840, 780, 740, 918

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

Apply this formula for all numbers.

Step1:

LCM(840, 780) = 10920

GCD(840, 780) = ( 840 x 780 ) / 10920

= 840 / 780

= 840

Step2:

LCM(60, 740) = 2220

GCD(60, 740) = ( 60 x 740 ) / 2220

= 60 / 740

= 60

Step3:

LCM(20, 918) = 9180

GCD(20, 918) = ( 20 x 918 ) / 9180

= 20 / 918

= 20

So, Greatest Common Divisor of 840, 780, 740, 918 is 2
