Given numbers are 445, 801, 689

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

Apply this formula for all numbers.

Step1:

LCM(445, 801) = 4005

GCD(445, 801) = ( 445 x 801 ) / 4005

= 445 / 801

= 445

Step2:

LCM(89, 689) = 61321

GCD(89, 689) = ( 89 x 689 ) / 61321

= 89 / 689

= 89

So, Greatest Common Divisor of 445, 801, 689 is 1
