Given numbers are 381, 640, 511, 976

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 511 are 7 x 73

Prime factors of 976 are 2 x 2 x 2 x 2 x 61

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

Given numbers are 381, 640, 511, 976

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

Apply this formula for all numbers.

Step1:

LCM(381, 640) = 243840

GCD(381, 640) = ( 381 x 640 ) / 243840

= 381 / 640

= 381

Step2:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

Step3:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

So, Greatest Common Divisor of 381, 640, 511, 976 is 1
