The list of prime factors of all numbers are
Prime factors of 531 are 3 x 3 x 59
Prime factors of 573 are 3 x 191
Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime factors of 646 are 2 x 17 x 19
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 531, 573, 432, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(531, 573) = 101421
GCD(531, 573) = ( 531 x 573 ) / 101421
= 531 / 573
= 531
Step2:
LCM(3, 432) = 432
GCD(3, 432) = ( 3 x 432 ) / 432
= 3 / 432
= 3
Step3:
LCM(3, 646) = 1938
GCD(3, 646) = ( 3 x 646 ) / 1938
= 3 / 646
= 3
So, Greatest Common Divisor of 531, 573, 432, 646 is 1
