Given numbers are 345,989,172,559

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

The LCM of 345,989,172,559 is 771420.

Find LCM of 345,989,172,559 with Prime Factorization

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

23 x 43 x 15 x 1 x 4 x 13 = 771420

Therefore, the lowest common multiple of 345,989,172,559 is 771420.

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 989 x 172 x 559 = 32806178340

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

989 : 1, 23, 43, 989

172 : 1, 2, 4, 43, 86, 172

559 : 1, 13, 43, 559

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,989,172,559, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

989:23x 43

172:2x 2x 43

559:13x 43

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

23x 43x 43 = 42527

Therefore, the value for common factors is 42527.

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 = 32806178340/(1x42527)

LCM = 32806178340/42527

LCM = 771420

Thus, we can understand that the LCM of 345,989,172,559 is 771420.
