Calculate the LCM of 351,731,724,939,390

Given numbers are 351,731,724,939,390

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

The LCM of 351,731,724,939,390 is 290721667860.

Find LCM of 351,731,724,939,390 with Prime Factorization


2 351, 731, 724, 939, 390
3 351, 731, 362, 939, 195
13 117, 731, 362, 313, 65
9, 731, 362, 313, 5

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

2 x 3 x 13 x 9 x 731 x 362 x 313 x 5 = 290721667860

Therefore, the lowest common multiple of 351,731,724,939,390 is 290721667860.

LCM Formula to Find Lowest Common Multiple of 351,731,724,939,390

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.

351 x 731 x 724 x 939 x 390 = 68028870279240

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

731 : 1, 17, 43, 731

724 : 1, 2, 4, 181, 362, 724

939 : 1, 3, 313, 939

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,731,724,939,390, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

731:17x 43

724:2x 2x 181

939:3x 313

390:2x 3x 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 3x 3x 13 = 234

Therefore, the value for common factors is 234.

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 = 68028870279240/(1x234)

LCM = 68028870279240/234

LCM = 290721667860

Thus, we can understand that the LCM of 351,731,724,939,390 is 290721667860.
