Given numbers are 143, 724, 421, 717

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

Apply this formula for all numbers.

Step1:

LCM(143, 724) = 103532

GCD(143, 724) = ( 143 x 724 ) / 103532

= 143 / 724

= 143

Step2:

LCM(1, 421) = 421

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

= 1 / 421

= 1

Step3:

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

= 1 / 717

= 1

So, Greatest Common Divisor of 143, 724, 421, 717 is 1
