Given numbers are 643, 491, 994, 554

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

Apply this formula for all numbers.

Step1:

LCM(643, 491) = 315713

GCD(643, 491) = ( 643 x 491 ) / 315713

= 643 / 491

= 643

Step2:

LCM(1, 994) = 994

GCD(1, 994) = ( 1 x 994 ) / 994

= 1 / 994

= 1

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 643, 491, 994, 554 is 1
