Given numbers are 646, 289, 565, 460

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

Apply this formula for all numbers.

Step1:

LCM(646, 289) = 10982

GCD(646, 289) = ( 646 x 289 ) / 10982

= 646 / 289

= 646

Step2:

LCM(17, 565) = 9605

GCD(17, 565) = ( 17 x 565 ) / 9605

= 17 / 565

= 17

Step3:

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

= 1 / 460

= 1

So, Greatest Common Divisor of 646, 289, 565, 460 is 1
