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

Apply this formula for all numbers.

Step1:

LCM(641, 255) = 163455

GCD(641, 255) = ( 641 x 255 ) / 163455

= 641 / 255

= 641

Step2:

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

= 1 / 89

= 1

So, Greatest Common Divisor of 641, 255, 89 is 1
