what is the highest common factor of 200 and 240
hi,
The fastest way to find the HCF of two numbers is to first prime factorise them,
200: 22255
240: 222235
Then take the common so; 2225
which is 40
The highest common factor of 200 and 240 is 40.
Given that,
Based on the above information, the calculation is as follows:
\(200 = 2\times 2\times 2\times 5\times 5\\\\240 = 2\times 2\times 2\times 2\times 3\times 5\)
Now the common factor is
\(= 2\times 2\times 2\times 5\)
= 40
Therefore we can conclude that The highest common factor of 200 and 240 is 40.
