Given numbers are 743,478,920

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

The LCM of 743,478,920 is 163370840.

Find LCM of 743,478,920 with Prime Factorization

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

2 x 743 x 239 x 460 = 163370840

Therefore, the lowest common multiple of 743,478,920 is 163370840.

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.

743 x 478 x 920 = 326741680

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.

743 : 1, 743

478 : 1, 2, 239, 478

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,478,920, is 1.

Now, the common factors can be found like this.

743:743

478:2x 239

920:2x 2x 2x 5x 23

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 = 326741680/(1x2)

LCM = 326741680/2

LCM = 163370840

Thus, we can understand that the LCM of 743,478,920 is 163370840.

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

• LCM of 969, 834, 948
