Given numbers are 644, 270, 278, 467

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 278 are 2 x 139

Prime factors of 467 are 467

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

Given numbers are 644, 270, 278, 467

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

Apply this formula for all numbers.

Step1:

LCM(644, 270) = 86940

GCD(644, 270) = ( 644 x 270 ) / 86940

= 644 / 270

= 644

Step2:

LCM(2, 278) = 278

GCD(2, 278) = ( 2 x 278 ) / 278

= 2 / 278

= 2

Step3:

LCM(2, 467) = 934

GCD(2, 467) = ( 2 x 467 ) / 934

= 2 / 467

= 2

So, Greatest Common Divisor of 644, 270, 278, 467 is 1
