Given numbers are 624, 243, 408, 783

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

Apply this formula for all numbers.

Step1:

LCM(624, 243) = 50544

GCD(624, 243) = ( 624 x 243 ) / 50544

= 624 / 243

= 624

Step2:

LCM(3, 408) = 408

GCD(3, 408) = ( 3 x 408 ) / 408

= 3 / 408

= 3

Step3:

LCM(3, 783) = 783

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

= 3 / 783

= 3

So, Greatest Common Divisor of 624, 243, 408, 783 is 3
