Given numbers are 740, 680, 78, 636

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

Apply this formula for all numbers.

Step1:

LCM(740, 680) = 25160

GCD(740, 680) = ( 740 x 680 ) / 25160

= 740 / 680

= 740

Step2:

LCM(20, 78) = 780

GCD(20, 78) = ( 20 x 78 ) / 780

= 20 / 78

= 20

Step3:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

So, Greatest Common Divisor of 740, 680, 78, 636 is 2
