Given numbers are 401, 289, 487, 763

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

Apply this formula for all numbers.

Step1:

LCM(401, 289) = 115889

GCD(401, 289) = ( 401 x 289 ) / 115889

= 401 / 289

= 401

Step2:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 401, 289, 487, 763 is 1
