Given numbers are 641, 455, 440

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

Apply this formula for all numbers.

Step1:

LCM(641, 455) = 291655

GCD(641, 455) = ( 641 x 455 ) / 291655

= 641 / 455

= 641

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 641, 455, 440 is 1
