Answer:The GCF is: 2The LCM is: 2402.)The GCF is:2The LCM is:936Step-by-step explanation:1.) GCF: All of the numbers have similar factorsgiven are: 60: 1,2,3,4,5,6,10,12,15,20,30 and 60. 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. 120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.LCM: Prime factorization of the numbers:60 = 2 × 2 × 3 × 580 = 2 × 2 × 2 × 2 × 5120 = 2 × 2 × 2 × 3 × 5LCM(60, 80, 120)= 2 × 2 × 2 × 2 × 3 × 5= 240.2.) GCF: All the numbers have similar factorsgiven are: 12: 1,2,3,4,6, and 12 18: 1,2,3,6,9,18 24: 1,2,3,4,6,8,12,24 26: 1, 2, 13, and 26.LCM: Prime factorization of the numbers:12 = 2 × 2 × 318 = 2 × 3 × 324 = 2 × 2 × 2 × 326 = 2 × 13LCM(12, 18, 24, 26)= 2 × 2 × 2 × 3 × 3 × 13= 936.
