Given numbers are 407, 387, 939, 636

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

Apply this formula for all numbers.

Step1:

LCM(407, 387) = 157509

GCD(407, 387) = ( 407 x 387 ) / 157509

= 407 / 387

= 407

Step2:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

Step3:

LCM(1, 636) = 636

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

= 1 / 636

= 1

So, Greatest Common Divisor of 407, 387, 939, 636 is 1
