To determine what goes into both 176 and 132 evenly, we need to find the greatest common factor (GCF) of the two numbers. The prime factorization of 176 is 2^4 * 11, and the prime factorization of 132 is 2^2 * 3 * 11. To find the GCF, we identify the common prime factors and take the smallest exponent for each factor, which gives us 2^2 * 11 = 44. Therefore, 44 is the largest number that goes into both 176 and 132 evenly.
Yes. 132 is evenly divisible by 11.
81 and 162 are both multiples of 3. In mathematics, a number that can be divided by another number without leaving a remainder is said to be divisible by that number. Both 81 and 162 can be evenly divided by 3, making them multiples of 3.
No, not evenly. 81 divided by 7 is 11 with remainder 4.
