Given numbers are 162, 980, 808, 290

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

Apply this formula for all numbers.

Step1:

LCM(162, 980) = 79380

GCD(162, 980) = ( 162 x 980 ) / 79380

= 162 / 980

= 162

Step2:

LCM(2, 808) = 808

GCD(2, 808) = ( 2 x 808 ) / 808

= 2 / 808

= 2

Step3:

LCM(2, 290) = 290

GCD(2, 290) = ( 2 x 290 ) / 290

= 2 / 290

= 2

So, Greatest Common Divisor of 162, 980, 808, 290 is 2
