Given numbers are 720, 547, 259, 686
The list of prime factors of all numbers are
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 547 are 547
Prime factors of 259 are 7 x 37
Prime factors of 686 are 2 x 7 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 720, 547, 259, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 547) = 393840
GCD(720, 547) = ( 720 x 547 ) / 393840
= 720 / 547
= 720
Step2:
LCM(1, 259) = 259
GCD(1, 259) = ( 1 x 259 ) / 259
= 1 / 259
= 1
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 720, 547, 259, 686 is 1
