Given numbers are 945,786,731,417,521

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

The LCM of 945,786,731,417,521 is 13106990973510.

Find LCM of 945,786,731,417,521 with Prime Factorization

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

3 x 315 x 262 x 731 x 139 x 521 = 13106990973510

Therefore, the lowest common multiple of 945,786,731,417,521 is 13106990973510.

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.

945 x 786 x 731 x 417 x 521 = 117962918761590

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.

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

786 : 1, 2, 3, 6, 131, 262, 393, 786

731 : 1, 17, 43, 731

417 : 1, 3, 139, 417

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,786,731,417,521, is 1.

Now, the common factors can be found like this.

945:3x 3x 3x 5x 7

786:2x 3x 131

731:17x 43

417:3x 139

521:521

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 117962918761590/(1x9)

LCM = 117962918761590/9

LCM = 13106990973510

Thus, we can understand that the LCM of 945,786,731,417,521 is 13106990973510.
