Question

Find the LCM of 25 and 120 by division method

Answer 1

Step-by-step explanation:

120=25 X4 +20

25=20X1+5

20=5X4+0

therefore hcf = 5

product of two nos. =lcm Xhcf

25 X 120= 5X lcm

lcm=600

HERE IS UR ANSWER ::--

To find Least Common Multiple by using Division Method we need to follow the following steps==)))

Step 1:

Write the given numbers in a horizontal line, separating them by commas.

Write the given numbers in a horizontal line, separating them by commas. Step 2:

Divide them by a suitable prime number, which exactly divides at least two of the given numbers.

Divide them by a suitable prime number, which exactly divides at least two of the given numbers.Step 3:

We put the quotient directly under the numbers in the next row. If the number is not divided exactly, we bring it down in the next row.

We put the quotient directly under the numbers in the next row. If the number is not divided exactly, we bring it down in the next row.Step 4:

We continue the process of step 2 and step 3 until all co-prime numbers are left in the last row.

We continue the process of step 2 and step 3 until all co-prime numbers are left in the last row.Step 5:

We multiply all the prime numbers by which we have divided and the co-prime numbers left in the last row. This product is the least common multiple of the given numbers.
