Given numbers are 349, 842, 808, 645

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

Apply this formula for all numbers.

Step1:

LCM(349, 842) = 293858

GCD(349, 842) = ( 349 x 842 ) / 293858

= 349 / 842

= 349

Step2:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 349, 842, 808, 645 is 1
