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

Apply this formula for all numbers.

Step1:

LCM(521, 133) = 69293

GCD(521, 133) = ( 521 x 133 ) / 69293

= 521 / 133

= 521

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 521, 133, 855 is 1
