Given numbers are 155, 444, 421

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

Apply this formula for all numbers.

Step1:

LCM(155, 444) = 68820

GCD(155, 444) = ( 155 x 444 ) / 68820

= 155 / 444

= 155

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 155, 444, 421 is 1
