Calculate the LCM of 442,920,234,685

Given numbers are 442,920,234,685

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

The LCM of 442,920,234,685 is 250693560.

Find LCM of 442,920,234,685 with Prime Factorization


2 442, 920, 234, 685
5 221, 460, 117, 685
13 221, 92, 117, 137
17, 92, 9, 137

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

2 x 5 x 13 x 17 x 92 x 9 x 137 = 250693560

Therefore, the lowest common multiple of 442,920,234,685 is 250693560.

LCM Formula to Find Lowest Common Multiple of 442,920,234,685

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.

442 x 920 x 234 x 685 = 65180325600

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,920,234,685, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

920:2x 2x 2x 5x 23

234:2x 3x 3x 13

685:5x 137

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 5x 13 = 260

Therefore, the value for common factors is 260.

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 = 65180325600/(1x260)

LCM = 65180325600/260

LCM = 250693560

Thus, we can understand that the LCM of 442,920,234,685 is 250693560.
