Given numbers are 491, 438, 437, 810

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

Apply this formula for all numbers.

Step1:

LCM(491, 438) = 215058

GCD(491, 438) = ( 491 x 438 ) / 215058

= 491 / 438

= 491

Step2:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 491, 438, 437, 810 is 1
