Given numbers are 401, 990, 197, 545

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

Apply this formula for all numbers.

Step1:

LCM(401, 990) = 396990

GCD(401, 990) = ( 401 x 990 ) / 396990

= 401 / 990

= 401

Step2:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 401, 990, 197, 545 is 1
