Calculate the LCM of 446,450,156,645

Given numbers are 446,450,156,645

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

The LCM of 446,450,156,645 is 112191300.

Find LCM of 446,450,156,645 with Prime Factorization


2 446, 450, 156, 645
3 223, 225, 78, 645
5 223, 75, 26, 215
223, 15, 26, 43

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

2 x 3 x 5 x 223 x 15 x 26 x 43 = 112191300

Therefore, the lowest common multiple of 446,450,156,645 is 112191300.

LCM Formula to Find Lowest Common Multiple of 446,450,156,645

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.

446 x 450 x 156 x 645 = 20194434000

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.

446 : 1, 2, 223, 446

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

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,450,156,645, is 1.

Now, the common factors can be found like this.

446:2x 223

450:2x 3x 3x 5x 5

156:2x 2x 3x 13

645:3x 5x 43

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 20194434000/(1x180)

LCM = 20194434000/180

LCM = 112191300

Thus, we can understand that the LCM of 446,450,156,645 is 112191300.
