Given numbers are 646, 340, 539, 906

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

Apply this formula for all numbers.

Step1:

LCM(646, 340) = 6460

GCD(646, 340) = ( 646 x 340 ) / 6460

= 646 / 340

= 646

Step2:

LCM(34, 539) = 18326

GCD(34, 539) = ( 34 x 539 ) / 18326

= 34 / 539

= 34

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 646, 340, 539, 906 is 1
