Given numbers are 517,742,780

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

The LCM of 517,742,780 is 149609460.

Find LCM of 517,742,780 with Prime Factorization

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

2 x 517 x 371 x 390 = 149609460

Therefore, the lowest common multiple of 517,742,780 is 149609460.

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.

517 x 742 x 780 = 299218920

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.

517 : 1, 11, 47, 517

742 : 1, 2, 7, 14, 53, 106, 371, 742

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,742,780, is 1.

Now, the common factors can be found like this.

517:11x 47

742:2x 7x 53

780:2x 2x 3x 5x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 299218920/(1x2)

LCM = 299218920/2

LCM = 149609460

Thus, we can understand that the LCM of 517,742,780 is 149609460.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 866, 144, 423
