Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5
Prime factors of 805 are 5 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 417, 828, 720, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(417, 828) = 115092
GCD(417, 828) = ( 417 x 828 ) / 115092
= 417 / 828
= 417
Step2:
LCM(3, 720) = 720
GCD(3, 720) = ( 3 x 720 ) / 720
= 3 / 720
= 3
Step3:
LCM(3, 805) = 2415
GCD(3, 805) = ( 3 x 805 ) / 2415
= 3 / 805
= 3
So, Greatest Common Divisor of 417, 828, 720, 805 is 1
