Calculate the LCM of 189,451,220,825

Given numbers are 189,451,220,825

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

The LCM of 189,451,220,825 is 8523900.

Find LCM of 189,451,220,825 with Prime Factorization


3 189, 451, 220, 825
5 63, 451, 220, 275
11 63, 451, 44, 55
63, 41, 4, 5

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

3 x 5 x 11 x 63 x 41 x 4 x 5 = 8523900

Therefore, the lowest common multiple of 189,451,220,825 is 8523900.

LCM Formula to Find Lowest Common Multiple of 189,451,220,825

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.

189 x 451 x 220 x 825 = 15470878500

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

451 : 1, 11, 41, 451

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,451,220,825, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

451:11x 41

220:2x 2x 5x 11

825:3x 5x 5x 11

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

3x 5x 11x 11 = 1815

Therefore, the value for common factors is 1815.

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 = 15470878500/(1x1815)

LCM = 15470878500/1815

LCM = 8523900

Thus, we can understand that the LCM of 189,451,220,825 is 8523900.
