Calculate the LCM of 731,513,102,345

Given numbers are 731,513,102,345

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

The LCM of 731,513,102,345 is 86250690.

Find LCM of 731,513,102,345 with Prime Factorization


3 731, 513, 102, 345
17 731, 171, 34, 115
43, 171, 2, 115

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

3 x 17 x 43 x 171 x 2 x 115 = 86250690

Therefore, the lowest common multiple of 731,513,102,345 is 86250690.

LCM Formula to Find Lowest Common Multiple of 731,513,102,345

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.

731 x 513 x 102 x 345 = 13196355570

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.

731 : 1, 17, 43, 731

513 : 1, 3, 9, 19, 27, 57, 171, 513

102 : 1, 2, 3, 6, 17, 34, 51, 102

345 : 1, 3, 5, 15, 23, 69, 115, 345

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,513,102,345, is 1.

Now, the common factors can be found like this.

731:17x 43

513:3x 3x 3x 19

102:2x 3x 17

345:3x 5x 23

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

3x 3x 17 = 153

Therefore, the value for common factors is 153.

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 = 13196355570/(1x153)

LCM = 13196355570/153

LCM = 86250690

Thus, we can understand that the LCM of 731,513,102,345 is 86250690.
