Given numbers are 421, 455, 801, 493

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

Apply this formula for all numbers.

Step1:

LCM(421, 455) = 191555

GCD(421, 455) = ( 421 x 455 ) / 191555

= 421 / 455

= 421

Step2:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 421, 455, 801, 493 is 1
