Given numbers are 215, 857, 877, 255

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

Apply this formula for all numbers.

Step1:

LCM(215, 857) = 184255

GCD(215, 857) = ( 215 x 857 ) / 184255

= 215 / 857

= 215

Step2:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

Step3:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

So, Greatest Common Divisor of 215, 857, 877, 255 is 1
