Question

find the LCM by Prime method 35 and 15
​

Answer 1

Answer:

LCM(15,35) = 105

Step-by-step explanation:

Answer:

HCF(15,35) = 5

LCM(15,35) = ( 15 × 35) / 5

LCM(15,35) = 525 / 5

LCM(15,35) = 105

Step-by-step explanation:

Prime Factorization of 15

Prime factors of 15 are 3, 5. Prime factorization of 15 in exponential form is:

15 = 3 × 5

Prime Factorization of 35

Prime factors of 35 are 5, 7. Prime factorization of 35 in exponential form is:

35 = 5 × 7

Now multiplying the highest exponent prime factors to calculate the LCM of 15 and 35.

LCM(15,35) = 31 × 51 × 71

LCM(15,35) = 105

Answer 2

Answer:

5 | 35 , 15

3 | 7 , 3

7 | 7 , 1

| 1 , 1

L.C.M of 35 and 15 : 5×3×7= 105
