Given numbers are 575, 644, 838, 420

The list of prime factors of all numbers are

Prime factors of 575 are 5 x 5 x 23

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

Prime factors of 838 are 2 x 419

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 575, 644, 838, 420

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

Apply this formula for all numbers.

Step1:

LCM(575, 644) = 16100

GCD(575, 644) = ( 575 x 644 ) / 16100

= 575 / 644

= 575

Step2:

LCM(23, 838) = 19274

GCD(23, 838) = ( 23 x 838 ) / 19274

= 23 / 838

= 23

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 575, 644, 838, 420 is 1
