Given numbers are 497, 891, 445, 816

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

Apply this formula for all numbers.

Step1:

LCM(497, 891) = 442827

GCD(497, 891) = ( 497 x 891 ) / 442827

= 497 / 891

= 497

Step2:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 497, 891, 445, 816 is 1
