Given numbers are 505, 835, 917, 438

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

Apply this formula for all numbers.

Step1:

LCM(505, 835) = 84335

GCD(505, 835) = ( 505 x 835 ) / 84335

= 505 / 835

= 505

Step2:

LCM(5, 917) = 4585

GCD(5, 917) = ( 5 x 917 ) / 4585

= 5 / 917

= 5

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 505, 835, 917, 438 is 1
