Given numbers are 636, 740, 434, 438

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

Apply this formula for all numbers.

Step1:

LCM(636, 740) = 117660

GCD(636, 740) = ( 636 x 740 ) / 117660

= 636 / 740

= 636

Step2:

LCM(4, 434) = 868

GCD(4, 434) = ( 4 x 434 ) / 868

= 4 / 434

= 4

Step3:

LCM(2, 438) = 438

GCD(2, 438) = ( 2 x 438 ) / 438

= 2 / 438

= 2

So, Greatest Common Divisor of 636, 740, 434, 438 is 2
