Given numbers are 644, 216, 246, 846

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

Apply this formula for all numbers.

Step1:

LCM(644, 216) = 34776

GCD(644, 216) = ( 644 x 216 ) / 34776

= 644 / 216

= 644

Step2:

LCM(4, 246) = 492

GCD(4, 246) = ( 4 x 246 ) / 492

= 4 / 246

= 4

Step3:

LCM(2, 846) = 846

GCD(2, 846) = ( 2 x 846 ) / 846

= 2 / 846

= 2

So, Greatest Common Divisor of 644, 216, 246, 846 is 2
