Given numbers are 646, 281, 436

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

Apply this formula for all numbers.

Step1:

LCM(646, 281) = 181526

GCD(646, 281) = ( 646 x 281 ) / 181526

= 646 / 281

= 646

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 646, 281, 436 is 1
