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

Apply this formula for all numbers.

Step1:

LCM(279, 656) = 183024

GCD(279, 656) = ( 279 x 656 ) / 183024

= 279 / 656

= 279

Step2:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1

So, Greatest Common Divisor of 279, 656, 65 is 1
