Given numbers are 903, 917, 643, 878

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

Apply this formula for all numbers.

Step1:

LCM(903, 917) = 118293

GCD(903, 917) = ( 903 x 917 ) / 118293

= 903 / 917

= 903

Step2:

LCM(7, 643) = 4501

GCD(7, 643) = ( 7 x 643 ) / 4501

= 7 / 643

= 7

Step3:

LCM(1, 878) = 878

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

= 1 / 878

= 1

So, Greatest Common Divisor of 903, 917, 643, 878 is 1
