Given numbers are 643, 675, 394, 634

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

Apply this formula for all numbers.

Step1:

LCM(643, 675) = 434025

GCD(643, 675) = ( 643 x 675 ) / 434025

= 643 / 675

= 643

Step2:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 643, 675, 394, 634 is 1
