Given numbers are 646, 850, 90

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

Apply this formula for all numbers.

Step1:

LCM(646, 850) = 16150

GCD(646, 850) = ( 646 x 850 ) / 16150

= 646 / 850

= 646

Step2:

LCM(34, 90) = 1530

GCD(34, 90) = ( 34 x 90 ) / 1530

= 34 / 90

= 34

So, Greatest Common Divisor of 646, 850, 90 is 2
