Calculate the LCM of 450,169,255,387

Given numbers are 450,169,255,387

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

The LCM of 450,169,255,387 is 55592550.

Find LCM of 450,169,255,387 with Prime Factorization


3 450, 169, 255, 387
3 150, 169, 85, 129
5 50, 169, 85, 43
10, 169, 17, 43

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

3 x 3 x 5 x 10 x 169 x 17 x 43 = 55592550

Therefore, the lowest common multiple of 450,169,255,387 is 55592550.

LCM Formula to Find Lowest Common Multiple of 450,169,255,387

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.

450 x 169 x 255 x 387 = 7504994250

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.

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

169 : 1, 13, 169

255 : 1, 3, 5, 15, 17, 51, 85, 255

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,169,255,387, is 1.

Now, the common factors can be found like this.

450:2x 3x 3x 5x 5

169:13x 13

255:3x 5x 17

387:3x 3x 43

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 5 = 135

Therefore, the value for common factors is 135.

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 = 7504994250/(1x135)

LCM = 7504994250/135

LCM = 55592550

Thus, we can understand that the LCM of 450,169,255,387 is 55592550.
