Given numbers are 291,971,147

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

The LCM of 291,971,147 is 13845489.

Find LCM of 291,971,147 with Prime Factorization

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

3 x 97 x 971 x 49 = 13845489

Therefore, the lowest common multiple of 291,971,147 is 13845489.

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.

291 x 971 x 147 = 41536467

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.

291 : 1, 3, 97, 291

971 : 1, 971

147 : 1, 3, 7, 21, 49, 147

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,971,147, is 1.

Now, the common factors can be found like this.

291:3x 97

971:971

147:3x 7x 7

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 = 41536467/(1x3)

LCM = 41536467/3

LCM = 13845489

Thus, we can understand that the LCM of 291,971,147 is 13845489.

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

• LCM of 866, 710, 403
• LCM of 828, 433, 133
• LCM of 678, 312, 990
