Given numbers are 354,449,430,421,830

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

The LCM of 354,449,430,421,830 is 1194120766770.

Find LCM of 354,449,430,421,830 with Prime Factorization

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

2 x 5 x 177 x 449 x 43 x 421 x 83 = 1194120766770

Therefore, the lowest common multiple of 354,449,430,421,830 is 1194120766770.

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.

354 x 449 x 430 x 421 x 830 = 23882415335400

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.

354 : 1, 2, 3, 6, 59, 118, 177, 354

449 : 1, 449

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

421 : 1, 421

830 : 1, 2, 5, 10, 83, 166, 415, 830

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,449,430,421,830, is 1.

Now, the common factors can be found like this.

354:2x 3x 59

449:449

430:2x 5x 43

421:421

830:2x 5x 83

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 5 = 20

Therefore, the value for common factors is 20.

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 = 23882415335400/(1x20)

LCM = 23882415335400/20

LCM = 1194120766770

Thus, we can understand that the LCM of 354,449,430,421,830 is 1194120766770.
