The LCM of 431,378,465,675 is 126261450.

Find LCM of 431,378,465,675 with Prime Factorization


3 431, 378, 465, 675
3 431, 126, 155, 225
3 431, 42, 155, 75
5 431, 14, 155, 25
431, 14, 31, 5

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

3 x 3 x 3 x 5 x 431 x 14 x 31 x 5 = 126261450

Therefore, the lowest common multiple of 431,378,465,675 is 126261450.

LCM Formula to Find Lowest Common Multiple of 431,378,465,675

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.

431 x 378 x 465 x 675 = 51135887250

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.

431 : 1, 431

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

465 : 1, 3, 5, 15, 31, 93, 155, 465

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,378,465,675, is 1.

Now, the common factors can be found like this.

431:431

378:2x 3x 3x 3x 7

465:3x 5x 31

675:3x 3x 3x 5x 5

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 3x 3x 5 = 405

Therefore, the value for common factors is 405.

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 = 51135887250/(1x405)

LCM = 51135887250/405

LCM = 126261450

Thus, we can understand that the LCM of 431,378,465,675 is 126261450.
