Given numbers are 636, 390, 717, 563

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

Apply this formula for all numbers.

Step1:

LCM(636, 390) = 41340

GCD(636, 390) = ( 636 x 390 ) / 41340

= 636 / 390

= 636

Step2:

LCM(6, 717) = 1434

GCD(6, 717) = ( 6 x 717 ) / 1434

= 6 / 717

= 6

Step3:

LCM(3, 563) = 1689

GCD(3, 563) = ( 3 x 563 ) / 1689

= 3 / 563

= 3

So, Greatest Common Divisor of 636, 390, 717, 563 is 1
