Given numbers are 756,439,556,102,680

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

The LCM of 756,439,556,102,680 is 7842418920.

Find LCM of 756,439,556,102,680 with Prime Factorization

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

2 x 2 x 3 x 17 x 63 x 439 x 139 x 1 x 10 = 7842418920

Therefore, the lowest common multiple of 756,439,556,102,680 is 7842418920.

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 439 x 556 x 102 x 680 = 12798827677440

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

439 : 1, 439

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

102 : 1, 2, 3, 6, 17, 34, 51, 102

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,439,556,102,680, is 1.

Now, the common factors can be found like this.

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

439:439

556:2x 2x 139

102:2x 3x 17

680:2x 2x 2x 5x 17

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 3x 17 = 1632

Therefore, the value for common factors is 1632.

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 = 12798827677440/(1x1632)

LCM = 12798827677440/1632

LCM = 7842418920

Thus, we can understand that the LCM of 756,439,556,102,680 is 7842418920.
