Calculate the LCM of 745,990,451,417

Given numbers are 745,990,451,417

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

The LCM of 745,990,451,417 is 840659490.

Find LCM of 745,990,451,417 with Prime Factorization


3 745, 990, 451, 417
5 745, 330, 451, 139
11 149, 66, 451, 139
149, 6, 41, 139

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

3 x 5 x 11 x 149 x 6 x 41 x 139 = 840659490

Therefore, the lowest common multiple of 745,990,451,417 is 840659490.

LCM Formula to Find Lowest Common Multiple of 745,990,451,417

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.

745 x 990 x 451 x 417 = 138708815850

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.

745 : 1, 5, 149, 745

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

451 : 1, 11, 41, 451

417 : 1, 3, 139, 417

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,990,451,417, is 1.

Now, the common factors can be found like this.

745:5x 149

990:2x 3x 3x 5x 11

451:11x 41

417:3x 139

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 11 = 165

Therefore, the value for common factors is 165.

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 = 138708815850/(1x165)

LCM = 138708815850/165

LCM = 840659490

Thus, we can understand that the LCM of 745,990,451,417 is 840659490.
