Given numbers are 340, 640, 64

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

Apply this formula for all numbers.

Step1:

LCM(340, 640) = 10880

GCD(340, 640) = ( 340 x 640 ) / 10880

= 340 / 640

= 340

Step2:

LCM(20, 64) = 320

GCD(20, 64) = ( 20 x 64 ) / 320

= 20 / 64

= 20

So, Greatest Common Divisor of 340, 640, 64 is 4
