Answer 2

Step-by-step explanation:

Given Find lcm of each number using factor tree

• 2 x 4, 2 x 7, 2 x 5
• Now consider 2 x 4
• So we can write this as 2 x 2 x 2
• 2 x 2 x 2  
• 2 x 7
• 2 x 5  
• 2 x 2 x 2 x 7 x 5 = 280
• So lcm is 280
• 3 x 8, 2 x 6, 3 x 5
• Now consider  
• 3 x 8
• 3 x 2 x 4
• 3 x 2 x 2 x 2
• Consider
• 2 x 6
• 2 x 2 x 3
• Consider  
• 3 x 5
• 3 x 2 x 2 x 2 x 5 = 120
• So lcm is 120
• 2 x 3, 2 x 12, 3 x 10
• 2 x 12
• 2 x 3 x 4
• 2 x 3 x 2 x 2
• 3 x 10
• 3 x 2 x 5
• 2 x 2 x 2 x 3 x 5 = 120
• So lcm is 120
