Given numbers are 203, 945, 742, 401

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

Apply this formula for all numbers.

Step1:

LCM(203, 945) = 27405

GCD(203, 945) = ( 203 x 945 ) / 27405

= 203 / 945

= 203

Step2:

LCM(7, 742) = 742

GCD(7, 742) = ( 7 x 742 ) / 742

= 7 / 742

= 7

Step3:

LCM(7, 401) = 2807

GCD(7, 401) = ( 7 x 401 ) / 2807

= 7 / 401

= 7

So, Greatest Common Divisor of 203, 945, 742, 401 is 1
