  1. Hitting 2 birds with one stone GCF and LCM using Prime factorization

  2. First, do a factor tree for both numbers 56 42 2 2 3 7 7 6 8 7 2 3 4 2 2 2 2

  3. GCF and LCM The GCF is everything in the intersection of the two circles multiplied. GCF = 2 ∙7 = 14 56 42 2 2 3 7 7 6 8 7 2 3 4 2 2 2 2 The LCM is everything in ALL of the two circles multiplied. LCM = 2 ∙ 2 ∙2 ∙3 ∙7 = 168
