Question

12) Find the LCM of 39, 45 and 54 13) Check the divisibility 1) 95100 by 10 2) 3979. by 3​

Answer 1

Answer:

step 1 Address input parameters & values.

Integers: 39 45 54

lcm (39, 45, 54) = ?

step 2 Arrange the group of numbers in the horizontal form with space or comma separated format

39, 45 and 54

step 3 Choose the divisor which divides each or most of the integers of in the group (39, 45 and 54), divide each integers separately and write down the quotient in the next line right under the respective integers. Bring down the integer to the next line if the integer is not divisible by the divisor. Repeat the same process until all the integers are brought to 1.

LCM of 39, 45 and 54

3 39 45 54

13 13 15 18

3 1 15 18

6 1 5 6

5 1 5 1

1 1 1

step 4 Multiply the divisors to find the lcm of 39, 45 and 54

3 x 13 x 3 x 6 x 5 = 3510

LCM(39, 45, 54) = 3510

The least common multiple for three numbers 39, 45 and 54 is 3510

Step-by-step explanation:

Answer 2

$Answer:$

1. LCM of 39, 45 and 54

⇒ 3 × 3 × 2 × 3 × 5 × 13

⇒ 3510

2. i) 95100 by 10

⇒ 95100 is divisible by 10.

⇒ 9510

ii) 3979 by 3.

⇒ 3979 is not divisible by 3.
