Given numbers are 546, 638, 223, 401

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

Apply this formula for all numbers.

Step1:

LCM(546, 638) = 174174

GCD(546, 638) = ( 546 x 638 ) / 174174

= 546 / 638

= 546

Step2:

LCM(2, 223) = 446

GCD(2, 223) = ( 2 x 223 ) / 446

= 2 / 223

= 2

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 546, 638, 223, 401 is 1
