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

Apply this formula for all numbers.

Step1:

LCM(521, 921) = 479841

GCD(521, 921) = ( 521 x 921 ) / 479841

= 521 / 921

= 521

Step2:

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

= 1 / 19

= 1

So, Greatest Common Divisor of 521, 921, 19 is 1
