Given numbers are 261, 486, 643, 503

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

Apply this formula for all numbers.

Step1:

LCM(261, 486) = 14094

GCD(261, 486) = ( 261 x 486 ) / 14094

= 261 / 486

= 261

Step2:

LCM(9, 643) = 5787

GCD(9, 643) = ( 9 x 643 ) / 5787

= 9 / 643

= 9

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 261, 486, 643, 503 is 1
