GCD of numbers is the greatest common divisor
So, the GCD (720, 261, 270, 720) = 9.
Given numbers are 720, 261, 270, 720
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 261 are 3 x 3 x 29
Prime factors of 270 are 2 x 3 x 3 x 3 x 5
Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
The highest common occurrence is 32
Therefore, GCD of 720, 261, 270, 720 is 9.
Given numbers are 720, 261, 270, 720
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 261) = 20880
GCD(720, 261) = ( 720 x 261 ) / 20880
= 720 / 261
= 720
Step2:
LCM(9, 270) = 270
GCD(9, 270) = ( 9 x 270 ) / 270
= 9 / 270
= 9
Step3:
LCM(9, 720) = 720
GCD(9, 720) = ( 9 x 720 ) / 720
= 9 / 720
= 9
So, Greatest Common Divisor of 720, 261, 270, 720 is 9
