Given numbers are 721, 413, 423, 487

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

Apply this formula for all numbers.

Step1:

LCM(721, 413) = 42539

GCD(721, 413) = ( 721 x 413 ) / 42539

= 721 / 413

= 721

Step2:

LCM(7, 423) = 2961

GCD(7, 423) = ( 7 x 423 ) / 2961

= 7 / 423

= 7

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 721, 413, 423, 487 is 1
