Given numbers are 407, 689, 395, 844

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

Apply this formula for all numbers.

Step1:

LCM(407, 689) = 280423

GCD(407, 689) = ( 407 x 689 ) / 280423

= 407 / 689

= 407

Step2:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 407, 689, 395, 844 is 1
