Given numbers are 423, 215, 726, 781

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

Apply this formula for all numbers.

Step1:

LCM(423, 215) = 90945

GCD(423, 215) = ( 423 x 215 ) / 90945

= 423 / 215

= 423

Step2:

LCM(1, 726) = 726

GCD(1, 726) = ( 1 x 726 ) / 726

= 1 / 726

= 1

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 423, 215, 726, 781 is 1
