Given numbers are 643, 412, 908, 803

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

Apply this formula for all numbers.

Step1:

LCM(643, 412) = 264916

GCD(643, 412) = ( 643 x 412 ) / 264916

= 643 / 412

= 643

Step2:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 643, 412, 908, 803 is 1
