Back to Tutor Intake Assessment: Find the greatest common factor and the least common multiple

6.NS.B.4 Tutor Intake -- GCF, LCM, and Factoring

This short check helps your tutor see where to start. Work on your own,
without a calculator. If you're unsure, give your best try — the goal is
to find what to work on together, not to grade you.

Concepts

What is the greatest common factor of $18$ and $35$ ?

Find the least common multiple of $4$ and $6$ by listing
multiples of each.

Procedures

Find the greatest common factor of $36$ and $24$ by listing
factors.

Using prime factorization ( $72 = 2^3 \times 3^2$ and
$108 = 2^2 \times 3^3$ ), find GCF $(72, 108)$ .

Using prime factorization ( $8 = 2^3$ and $12 = 2^2 \times 3$ ),
what is LCM $(8, 12)$ ?

Express $24 + 36$ as the GCF times a sum of two coprime numbers:
$24 + 36 = $ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ $\times ($ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ $ + $ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ ̲ $)$ .
