Given numbers are 715,40,553

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

The LCM of 715,40,553 is 3163160.

Find LCM of 715,40,553 with Prime Factorization

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

5 x 143 x 8 x 553 = 3163160

Therefore, the lowest common multiple of 715,40,553 is 3163160.

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.

715 x 40 x 553 = 15815800

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

40 : 1, 2, 4, 5, 8, 10, 20, 40

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,40,553, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

40:2x 2x 2x 5

553:7x 79

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

5 = 5

Therefore, the value for common factors is 5.

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 = 15815800/(1x5)

LCM = 15815800/5

LCM = 3163160

Thus, we can understand that the LCM of 715,40,553 is 3163160.

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

• LCM of 478, 87, 512
• LCM of 177, 28, 950
