Given numbers are 381, 324, 620, 419

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 419 are 419

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

Given numbers are 381, 324, 620, 419

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

Apply this formula for all numbers.

Step1:

LCM(381, 324) = 41148

GCD(381, 324) = ( 381 x 324 ) / 41148

= 381 / 324

= 381

Step2:

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 381, 324, 620, 419 is 1
