find the lcm and hcf of 24, 15, 36 by prime factorisation method
Answers
Answer:
LCM is 360, HCF is 3.
Step-by-step explanation:
LCM:
2 24,15,36
2 12,15,18
2 6,15,9
3 3,15,9
3 1,5,3
5 1,5,1
1,1,1
Therefore, LCM of 24, 15 and 36 is 2*2*2*3*3*5= 360
HCF:
2 24 3 15 2 36
2 12 5 5 2 18
2 6 1 3 9
3 3 3 3
1 1
24=2*2*2*3
15=3*5
36=2*2*3*3
Therefore, the HCF of 24, 15 and 36 is 3.
Answer:
First, find the prime factors of the given integers: 24, 15 and 36
For, 24 = 2 × 2 x 2 x 3
15 = 3 × 5
36 = 2 × 2 × 3 × 3
Now, LCM of 24, 15 and 36 = 2 × 2 × 2 × 3 × 3 × 5
∴ LCM (24, 15, 36) = 360
And, HCF (24, 15 and 36) = 3
