Given numbers are 429,471,947

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

The LCM of 429,471,947 is 63783291.

Find LCM of 429,471,947 with Prime Factorization

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

3 x 143 x 157 x 947 = 63783291

Therefore, the lowest common multiple of 429,471,947 is 63783291.

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.

429 x 471 x 947 = 191349873

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.

429 : 1, 3, 11, 13, 33, 39, 143, 429

471 : 1, 3, 157, 471

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,471,947, is 1.

Now, the common factors can be found like this.

429:3x 11x 13

471:3x 157

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 191349873/(1x3)

LCM = 191349873/3

LCM = 63783291

Thus, we can understand that the LCM of 429,471,947 is 63783291.

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

• LCM of 131, 436, 189
• LCM of 235, 853, 877
• LCM of 388, 367, 712
