Given numbers are 666, 326, 40, 455

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

Apply this formula for all numbers.

Step1:

LCM(666, 326) = 108558

GCD(666, 326) = ( 666 x 326 ) / 108558

= 666 / 326

= 666

Step2:

LCM(2, 40) = 40

GCD(2, 40) = ( 2 x 40 ) / 40

= 2 / 40

= 2

Step3:

LCM(2, 455) = 910

GCD(2, 455) = ( 2 x 455 ) / 910

= 2 / 455

= 2

So, Greatest Common Divisor of 666, 326, 40, 455 is 1
