Given numbers are 643, 308, 326, 627

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

Apply this formula for all numbers.

Step1:

LCM(643, 308) = 198044

GCD(643, 308) = ( 643 x 308 ) / 198044

= 643 / 308

= 643

Step2:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

Step3:

LCM(1, 627) = 627

GCD(1, 627) = ( 1 x 627 ) / 627

= 1 / 627

= 1

So, Greatest Common Divisor of 643, 308, 326, 627 is 1
