The method (List and match): Factor: divides with no remainder. Multiple: appears in the table. HCF: list the factors of both numbers; take the biggest one they share. LCM: list the multiples of the bigger number; take the first one the smaller number also divides. Prime: exactly 2 factors (2, 3, 5, 7, 11 …). 1 is not prime.
