Given numbers are 421, 442, 549, 473

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

Apply this formula for all numbers.

Step1:

LCM(421, 442) = 186082

GCD(421, 442) = ( 421 x 442 ) / 186082

= 421 / 442

= 421

Step2:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

Step3:

LCM(1, 473) = 473

GCD(1, 473) = ( 1 x 473 ) / 473

= 1 / 473

= 1

So, Greatest Common Divisor of 421, 442, 549, 473 is 1
