Given numbers are 890, 148, 161, 809

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

Apply this formula for all numbers.

Step1:

LCM(890, 148) = 65860

GCD(890, 148) = ( 890 x 148 ) / 65860

= 890 / 148

= 890

Step2:

LCM(2, 161) = 322

GCD(2, 161) = ( 2 x 161 ) / 322

= 2 / 161

= 2

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 890, 148, 161, 809 is 1
