Given numbers are 646, 960, 108, 609

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

Apply this formula for all numbers.

Step1:

LCM(646, 960) = 310080

GCD(646, 960) = ( 646 x 960 ) / 310080

= 646 / 960

= 646

Step2:

LCM(2, 108) = 108

GCD(2, 108) = ( 2 x 108 ) / 108

= 2 / 108

= 2

Step3:

LCM(2, 609) = 1218

GCD(2, 609) = ( 2 x 609 ) / 1218

= 2 / 609

= 2

So, Greatest Common Divisor of 646, 960, 108, 609 is 1
