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

Apply this formula for all numbers.

Step1:

LCM(417, 387) = 53793

GCD(417, 387) = ( 417 x 387 ) / 53793

= 417 / 387

= 417

Step2:

LCM(3, 783) = 783

GCD(3, 783) = ( 3 x 783 ) / 783

= 3 / 783

= 3

Step3:

LCM(3, 636) = 636

GCD(3, 636) = ( 3 x 636 ) / 636

= 3 / 636

= 3

So, Greatest Common Divisor of 417, 387, 783, 636 is 3
