Given numbers are 709,905,646,556

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

The LCM of 709,905,646,556 is 115231742260.

Find LCM of 709,905,646,556 with Prime Factorization

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

2 x 709 x 905 x 323 x 278 = 115231742260

Therefore, the lowest common multiple of 709,905,646,556 is 115231742260.

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.

709 x 905 x 646 x 556 = 230463484520

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.

709 : 1, 709

905 : 1, 5, 181, 905

646 : 1, 2, 17, 19, 34, 38, 323, 646

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,905,646,556, is 1.

Now, the common factors can be found like this.

709:709

905:5x 181

646:2x 17x 19

556:2x 2x 139

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

2 = 2

Therefore, the value for common factors is 2.

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 = 230463484520/(1x2)

LCM = 230463484520/2

LCM = 115231742260

Thus, we can understand that the LCM of 709,905,646,556 is 115231742260.
