Given numbers are 756,644,283,388,672

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

The LCM of 756,644,283,388,672 is 3818543904.

Find LCM of 756,644,283,388,672 with Prime Factorization

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

2 x 2 x 3 x 7 x 9 x 23 x 283 x 97 x 8 = 3818543904

Therefore, the lowest common multiple of 756,644,283,388,672 is 3818543904.

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.

756 x 644 x 283 x 388 x 672 = 35924861048832

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.

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

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

283 : 1, 283

388 : 1, 2, 4, 97, 194, 388

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,644,283,388,672, is 1.

Now, the common factors can be found like this.

756:2x 2x 3x 3x 3x 7

644:2x 2x 7x 23

283:283

388:2x 2x 97

672:2x 2x 2x 2x 2x 3x 7

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 2x 2x 3x 7x 7 = 9408

Therefore, the value for common factors is 9408.

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 = 35924861048832/(1x9408)

LCM = 35924861048832/9408

LCM = 3818543904

Thus, we can understand that the LCM of 756,644,283,388,672 is 3818543904.
