Given numbers are 643, 726, 687, 292

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

Apply this formula for all numbers.

Step1:

LCM(643, 726) = 466818

GCD(643, 726) = ( 643 x 726 ) / 466818

= 643 / 726

= 643

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 292) = 292

GCD(1, 292) = ( 1 x 292 ) / 292

= 1 / 292

= 1

So, Greatest Common Divisor of 643, 726, 687, 292 is 1
