Answer 1

Answer:

Hope my answer helps you :-)

Step-by-step explanation:

Find the prime factorization of 45

Find the prime factorization of 4545 = 3 × 3 × 5

Find the prime factorization of 4545 = 3 × 3 × 5Find the prime factorization of 70

Find the prime factorization of 4545 = 3 × 3 × 5Find the prime factorization of 7070 = 2 × 5 × 7

Find the prime factorization of 4545 = 3 × 3 × 5Find the prime factorization of 7070 = 2 × 5 × 7Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm:

HCF=5

Hcf *lcm = product of two number

630*5=45*70

3150=3150

Answer 2

Answer:

Mate, the required answer is here..

Step-by-step explanation:

45 = 3 x 5 x 3

70 = 2 x 5 x 7

LCM = 5 x 3 x3 x 2 x 7 = 630

HCF =5

LCM x HCF = product of the numbers.

630 x 5 = 45 x 70 = 3150.
