Given numbers are 946,720,257

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

The LCM of 946,720,257 is 87523920.

Find LCM of 946,720,257 with Prime Factorization

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

2 x 473 x 360 x 257 = 87523920

Therefore, the lowest common multiple of 946,720,257 is 87523920.

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.

946 x 720 x 257 = 175047840

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,720,257, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

720:2x 2x 2x 2x 3x 3x 5

257:257

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 = 175047840/(1x2)

LCM = 175047840/2

LCM = 87523920

Thus, we can understand that the LCM of 946,720,257 is 87523920.

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

• LCM of 616, 691, 339
