Given numbers are 643, 816, 390, 294

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

Apply this formula for all numbers.

Step1:

LCM(643, 816) = 524688

GCD(643, 816) = ( 643 x 816 ) / 524688

= 643 / 816

= 643

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 294) = 294

GCD(1, 294) = ( 1 x 294 ) / 294

= 1 / 294

= 1

So, Greatest Common Divisor of 643, 816, 390, 294 is 1
