Given numbers are 742, 987, 909, 636

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

Apply this formula for all numbers.

Step1:

LCM(742, 987) = 104622

GCD(742, 987) = ( 742 x 987 ) / 104622

= 742 / 987

= 742

Step2:

LCM(7, 909) = 6363

GCD(7, 909) = ( 7 x 909 ) / 6363

= 7 / 909

= 7

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 742, 987, 909, 636 is 1
