Calculate the LCM of 485,728,525,442

Given numbers are 485,728,525,442

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

The LCM of 485,728,525,442 is 90035400.

Find LCM of 485,728,525,442 with Prime Factorization


2 485, 728, 525, 442
5 485, 364, 525, 221
7 97, 364, 105, 221
13 97, 52, 15, 221
97, 4, 15, 17

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

2 x 5 x 7 x 13 x 97 x 4 x 15 x 17 = 90035400

Therefore, the lowest common multiple of 485,728,525,442 is 90035400.

LCM Formula to Find Lowest Common Multiple of 485,728,525,442

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.

485 x 728 x 525 x 442 = 81932214000

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.

485 : 1, 5, 97, 485

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,728,525,442, is 1.

Now, the common factors can be found like this.

485:5x 97

728:2x 2x 2x 7x 13

525:3x 5x 5x 7

442:2x 13x 17

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

2x 5x 7x 13 = 910

Therefore, the value for common factors is 910.

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 = 81932214000/(1x910)

LCM = 81932214000/910

LCM = 90035400

Thus, we can understand that the LCM of 485,728,525,442 is 90035400.
