Full solution

Q. What is the greatest common factor of 8m2,4m 8 m^{2}, 4 m , and 10m4 10 m^{4} ?
  1. List Prime Factors: List the prime factors of each term.\newlineFor 8m28m^2, the prime factors are 23×m22^3 \times m^2.\newlineFor 4m4m, the prime factors are 22×m2^2 \times m.\newlineFor 10m410m^4, the prime factors are 2×5×m42 \times 5 \times m^4.
  2. Identify Common Factors: Identify the common prime factors.\newlineThe common prime factors of 8m28m^2, 4m4m, and 10m410m^4 are 22 and mm, since these are the only prime factors that appear in all three terms.
  3. Determine Lowest Power: Determine the lowest power of the common prime factors.\newlineThe lowest power of 22 that appears in all terms is 212^1 (from 10m410m^4).\newlineThe lowest power of mm that appears in all terms is m1m^1 (from 4m4m).
  4. Find GCF: Multiply the common prime factors with their lowest powers to find the GCF.\newlineThe GCF is 21×m12^1 \times m^1, which simplifies to 2m2m.
