Given numbers are 643, 606, 388, 901

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

Apply this formula for all numbers.

Step1:

LCM(643, 606) = 389658

GCD(643, 606) = ( 643 x 606 ) / 389658

= 643 / 606

= 643

Step2:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

Step3:

LCM(1, 901) = 901

GCD(1, 901) = ( 1 x 901 ) / 901

= 1 / 901

= 1

So, Greatest Common Divisor of 643, 606, 388, 901 is 1
