Given numbers are 915, 191, 531, 857

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

Apply this formula for all numbers.

Step1:

LCM(915, 191) = 174765

GCD(915, 191) = ( 915 x 191 ) / 174765

= 915 / 191

= 915

Step2:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 915, 191, 531, 857 is 1
