Given numbers are 406, 287, 890, 665

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

Apply this formula for all numbers.

Step1:

LCM(406, 287) = 16646

GCD(406, 287) = ( 406 x 287 ) / 16646

= 406 / 287

= 406

Step2:

LCM(7, 890) = 6230

GCD(7, 890) = ( 7 x 890 ) / 6230

= 7 / 890

= 7

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 406, 287, 890, 665 is 1
