Calculate the LCM of 3,858,950,646

Given numbers are 3,858,950,646

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

The LCM of 3,858,950,646 is 6928350.

Find LCM of 3,858,950,646 with Prime Factorization


2 3, 858, 950, 646
3 3, 429, 475, 323
19 1, 143, 475, 323
1, 143, 25, 17

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

2 x 3 x 19 x 1 x 143 x 25 x 17 = 6928350

Therefore, the lowest common multiple of 3,858,950,646 is 6928350.

LCM Formula to Find Lowest Common Multiple of 3,858,950,646

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.

3 x 858 x 950 x 646 = 1579663800

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.

3 : 1, 3

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,858,950,646, is 1.

Now, the common factors can be found like this.

3:3

858:2x 3x 11x 13

950:2x 5x 5x 19

646:2x 17x 19

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 19 = 228

Therefore, the value for common factors is 228.

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 = 1579663800/(1x228)

LCM = 1579663800/228

LCM = 6928350

Thus, we can understand that the LCM of 3,858,950,646 is 6928350.
