Given numbers are 374, 386, 646, 643

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

Apply this formula for all numbers.

Step1:

LCM(374, 386) = 72182

GCD(374, 386) = ( 374 x 386 ) / 72182

= 374 / 386

= 374

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 374, 386, 646, 643 is 1
