Given numbers are 643, 783, 926, 287

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

Apply this formula for all numbers.

Step1:

LCM(643, 783) = 503469

GCD(643, 783) = ( 643 x 783 ) / 503469

= 643 / 783

= 643

Step2:

LCM(1, 926) = 926

GCD(1, 926) = ( 1 x 926 ) / 926

= 1 / 926

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 643, 783, 926, 287 is 1
