Given numbers are 497, 287, 664, 878

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

Apply this formula for all numbers.

Step1:

LCM(497, 287) = 20377

GCD(497, 287) = ( 497 x 287 ) / 20377

= 497 / 287

= 497

Step2:

LCM(7, 664) = 4648

GCD(7, 664) = ( 7 x 664 ) / 4648

= 7 / 664

= 7

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 497, 287, 664, 878 is 1
