Given numbers are 550,390,971,956,130

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

The LCM of 550,390,971,956,130 is 9955760100.

Find LCM of 550,390,971,956,130 with Prime Factorization

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

2 x 5 x 13 x 55 x 3 x 971 x 478 x 1 = 9955760100

Therefore, the lowest common multiple of 550,390,971,956,130 is 9955760100.

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.

550 x 390 x 971 x 956 x 130 = 25884976260000

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.

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

971 : 1, 971

956 : 1, 2, 4, 239, 478, 956

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,390,971,956,130, is 1.

Now, the common factors can be found like this.

550:2x 5x 5x 11

390:2x 3x 5x 13

971:971

956:2x 2x 239

130:2x 5x 13

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

2x 2x 2x 5x 5x 13 = 2600

Therefore, the value for common factors is 2600.

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 = 25884976260000/(1x2600)

LCM = 25884976260000/2600

LCM = 9955760100

Thus, we can understand that the LCM of 550,390,971,956,130 is 9955760100.
