Answer:
LCM is 120. GCF is 8.
Step-by-step explanation:
LCM of 24: 3 and 8,
2, 4
2, 2
You need to prime factorize first so 24: 2 x 2 x 2 x 3
LCM of 40: 4 and 10
2, 2 2, 5
So 2 x 2 x 2 x 5
Greater number of each of them: 2 x 2 x 2 x 3 x 5= 120
GCF of 24:
Factors of 24: 1, 2, 3, 4, 6, 8, 12
Factors of 80: 1, 2, 4, 5, 8, 10, 20
So the GCF is 8
