Given numbers are 646, 275, 471, 908

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

Apply this formula for all numbers.

Step1:

LCM(646, 275) = 177650

GCD(646, 275) = ( 646 x 275 ) / 177650

= 646 / 275

= 646

Step2:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

Step3:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

So, Greatest Common Divisor of 646, 275, 471, 908 is 1
