Seven goes into both 63 and 77
To find the highest common factor (HCF) of 77, 132, and 143, we first need to break down each number into its prime factors. 77 = 7 x 11 132 = 2^2 x 3 x 11 143 = 11 x 13 Next, we identify the common prime factors among the numbers, which are 11. Therefore, the HCF of 77, 132, and 143 is 11.
There is really no such thing as a "highest common multiple". Once you find a common multiple of a set of numbers, you can keep adding the CM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
To multiply a number by 11, you can add the original number to itself with a zero inserted between the digits. In this case, 11 x 132 can be calculated as 132 + (132 x 10) = 132 + 1320 = 1452.
77 over 10 = 77/10
