Given numbers are 345,163,556,430

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

The LCM of 345,163,556,430 is 1344466380.

Find LCM of 345,163,556,430 with Prime Factorization

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

2 x 5 x 69 x 163 x 278 x 43 = 1344466380

Therefore, the lowest common multiple of 345,163,556,430 is 1344466380.

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.

345 x 163 x 556 x 430 = 13444663800

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

163 : 1, 163

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,163,556,430, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

163:163

556:2x 2x 139

430:2x 5x 43

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 13444663800/(1x10)

LCM = 13444663800/10

LCM = 1344466380

Thus, we can understand that the LCM of 345,163,556,430 is 1344466380.
