Given numbers are 646, 416, 163, 909

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

Apply this formula for all numbers.

Step1:

LCM(646, 416) = 134368

GCD(646, 416) = ( 646 x 416 ) / 134368

= 646 / 416

= 646

Step2:

LCM(2, 163) = 326

GCD(2, 163) = ( 2 x 163 ) / 326

= 2 / 163

= 2

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 646, 416, 163, 909 is 1
