Given numbers are 130,991,278

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

The LCM of 130,991,278 is 17907370.

Find LCM of 130,991,278 with Prime Factorization

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

2 x 65 x 991 x 139 = 17907370

Therefore, the lowest common multiple of 130,991,278 is 17907370.

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.

130 x 991 x 278 = 35814740

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.

130 : 1, 2, 5, 10, 13, 26, 65, 130

991 : 1, 991

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,991,278, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

991:991

278:2x 139

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 = 35814740/(1x2)

LCM = 35814740/2

LCM = 17907370

Thus, we can understand that the LCM of 130,991,278 is 17907370.

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

• LCM of 712, 676, 319
• LCM of 244, 212, 831
• LCM of 426, 322, 819
