Given numbers are 756,556,524,638

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

The LCM of 756,556,524,638 is 4391355276.

Find LCM of 756,556,524,638 with Prime Factorization

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

2 x 2 x 189 x 139 x 131 x 319 = 4391355276

Therefore, the lowest common multiple of 756,556,524,638 is 4391355276.

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 556 x 524 x 638 = 140523368832

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

556 : 1, 2, 4, 139, 278, 556

524 : 1, 2, 4, 131, 262, 524

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,556,524,638, is 2.

Now, the common factors can be found like this.

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

556:2x 2x 139

524:2x 2x 131

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 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 140523368832/(2x16)

LCM = 140523368832/32

LCM = 4391355276

Thus, we can understand that the LCM of 756,556,524,638 is 4391355276.
