Given numbers are 661, 440, 431

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

Apply this formula for all numbers.

Step1:

LCM(661, 440) = 290840

GCD(661, 440) = ( 661 x 440 ) / 290840

= 661 / 440

= 661

Step2:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

So, Greatest Common Divisor of 661, 440, 431 is 1
