Given numbers are 87,435,947

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

The LCM of 87,435,947 is 411945.

Find LCM of 87,435,947 with Prime Factorization

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

3 x 29 x 1 x 5 x 947 = 411945

Therefore, the lowest common multiple of 87,435,947 is 411945.

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.

87 x 435 x 947 = 35839215

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.

87 : 1, 3, 29, 87

435 : 1, 3, 5, 15, 29, 87, 145, 435

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 87,435,947, is 1.

Now, the common factors can be found like this.

87:3x 29

435:3x 5x 29

947:947

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

3x 29 = 87

Therefore, the value for common factors is 87.

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 = 35839215/(1x87)

LCM = 35839215/87

LCM = 411945

Thus, we can understand that the LCM of 87,435,947 is 411945.

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

• LCM of 12, 376, 507
• LCM of 19, 316, 436
