Given numbers are 531, 253, 465, 687
The list of prime factors of all numbers are
Prime factors of 531 are 3 x 3 x 59
Prime factors of 253 are 11 x 23
Prime factors of 465 are 3 x 5 x 31
Prime factors of 687 are 3 x 229
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 531, 253, 465, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(531, 253) = 134343
GCD(531, 253) = ( 531 x 253 ) / 134343
= 531 / 253
= 531
Step2:
LCM(1, 465) = 465
GCD(1, 465) = ( 1 x 465 ) / 465
= 1 / 465
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 531, 253, 465, 687 is 1
