Given numbers are 531, 644, 497, 857

The list of prime factors of all numbers are

Prime factors of 531 are 3 x 3 x 59

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

Prime factors of 497 are 7 x 71

Prime factors of 857 are 857

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

Given numbers are 531, 644, 497, 857

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

Apply this formula for all numbers.

Step1:

LCM(531, 644) = 341964

GCD(531, 644) = ( 531 x 644 ) / 341964

= 531 / 644

= 531

Step2:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 531, 644, 497, 857 is 1
