Given numbers are 724, 868, 445, 243

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

Apply this formula for all numbers.

Step1:

LCM(724, 868) = 157108

GCD(724, 868) = ( 724 x 868 ) / 157108

= 724 / 868

= 724

Step2:

LCM(4, 445) = 1780

GCD(4, 445) = ( 4 x 445 ) / 1780

= 4 / 445

= 4

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 724, 868, 445, 243 is 1
