Calculate the LCM of 643,643,444,638

Given numbers are 643,643,444,638

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

The LCM of 643,643,444,638 is 91071948.

Find LCM of 643,643,444,638 with Prime Factorization

2	643, 643, 444, 638
643	643, 643, 222, 319
	1, 1, 222, 319

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

2 x 643 x 1 x 1 x 222 x 319 = 91071948

Therefore, the lowest common multiple of 643,643,444,638 is 91071948.

LCM Formula to Find Lowest Common Multiple of 643,643,444,638

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.

643 x 643 x 444 x 638 = 117118525128

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.

643 : 1, 643

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,643,444,638, is 1.

Now, the common factors can be found like this.

643:643

444:2x 2x 3x 37

638:2x 11x 29

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

2x 643 = 1286

Therefore, the value for common factors is 1286.

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 = 117118525128/(1x1286)

LCM = 117118525128/1286

LCM = 91071948

Thus, we can understand that the LCM of 643,643,444,638 is 91071948.
