Given numbers are 404, 890, 646, 909

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

Apply this formula for all numbers.

Step1:

LCM(404, 890) = 179780

GCD(404, 890) = ( 404 x 890 ) / 179780

= 404 / 890

= 404

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 909) = 1818

GCD(2, 909) = ( 2 x 909 ) / 1818

= 2 / 909

= 2

So, Greatest Common Divisor of 404, 890, 646, 909 is 1
