Given numbers are 1378,2470

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 1378,2470 is 130910.

Find LCM of 1378,2470 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 13 x 53 x 95 = 130910

Therefore, the lowest common multiple of 1378,2470 is 130910.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

1378 x 2470 = 3403660

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

1378 : 1, 2, 13, 26, 53, 106, 689, 1378

2470 : 1, 2, 5, 10, 13, 19, 26, 38, 65, 95, 130, 190, 247, 494, 1235, 2470

26 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1378,2470, is 26.

Now, the common factors can be found like this.

1378:2x 13x 53

2470:2x 5x 13x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

= 1

Therefore, the value for common factors is 1.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 3403660/(26x1)

LCM = 3403660/26

LCM = 130910

Thus, we can understand that the LCM of 1378,2470 is 130910.
