Given numbers are 644,462,787,252,906

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

The LCM of 644,462,787,252,906 is 7576571772.

Find LCM of 644,462,787,252,906 with Prime Factorization

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

2 x 2 x 3 x 7 x 23 x 11 x 787 x 3 x 151 = 7576571772

Therefore, the lowest common multiple of 644,462,787,252,906 is 7576571772.

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.

644 x 462 x 787 x 252 x 906 = 53460290423232

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

787 : 1, 787

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

906 : 1, 2, 3, 6, 151, 302, 453, 906

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,462,787,252,906, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

462:2x 3x 7x 11

787:787

252:2x 2x 3x 3x 7

906:2x 3x 151

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 2x 2x 3x 3x 7x 7 = 7056

Therefore, the value for common factors is 7056.

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 = 53460290423232/(1x7056)

LCM = 53460290423232/7056

LCM = 7576571772

Thus, we can understand that the LCM of 644,462,787,252,906 is 7576571772.
