Given numbers are 815, 917, 178, 479

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

Apply this formula for all numbers.

Step1:

LCM(815, 917) = 747355

GCD(815, 917) = ( 815 x 917 ) / 747355

= 815 / 917

= 815

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 815, 917, 178, 479 is 1
