Given numbers are 720, 445, 432, 249
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 445 are 5 x 89
Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime factors of 249 are 3 x 83
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 720, 445, 432, 249
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 445) = 64080
GCD(720, 445) = ( 720 x 445 ) / 64080
= 720 / 445
= 720
Step2:
LCM(5, 432) = 2160
GCD(5, 432) = ( 5 x 432 ) / 2160
= 5 / 432
= 5
Step3:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
So, Greatest Common Divisor of 720, 445, 432, 249 is 1
