Given numbers are 102, 439, 21

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

Apply this formula for all numbers.

Step1:

LCM(102, 439) = 44778

GCD(102, 439) = ( 102 x 439 ) / 44778

= 102 / 439

= 102

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

So, Greatest Common Divisor of 102, 439, 21 is 1
