Given numbers are 648, 476, 381, 394

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 381 are 3 x 127

Prime factors of 394 are 2 x 197

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 648, 476, 381, 394

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

Apply this formula for all numbers.

Step1:

LCM(648, 476) = 77112

GCD(648, 476) = ( 648 x 476 ) / 77112

= 648 / 476

= 648

Step2:

LCM(4, 381) = 1524

GCD(4, 381) = ( 4 x 381 ) / 1524

= 4 / 381

= 4

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 648, 476, 381, 394 is 1
