Given numbers are 808, 162, 497, 455

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

Apply this formula for all numbers.

Step1:

LCM(808, 162) = 65448

GCD(808, 162) = ( 808 x 162 ) / 65448

= 808 / 162

= 808

Step2:

LCM(2, 497) = 994

GCD(2, 497) = ( 2 x 497 ) / 994

= 2 / 497

= 2

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 808, 162, 497, 455 is 1
