Lesson 2 (02) Investigation - Family "DO"

Family "DO":
58, 74, 102, 50, 46, 282

(a) Describe as many relationship(s) as you could about the numbers.
(b) Add 3 members to Family "DO" that satisfy the relationship(s) you described in (a)

Note correction for the prime factorisation of the last number "282".
282 could be expressed as 2 x 2 x 47 (i.e. 2^2 x 47)

  • There is no change to the HCF
  • However, for LCM, it would be 2 x 3 x 5^2 x 17 x 23 x 29 x 37 x 47, which is the same as 2,957,778,150
