Given numbers are 688,430,194,842

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

The LCM of 688,430,194,842 is 140479280.

Find LCM of 688,430,194,842 with Prime Factorization

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

2 x 43 x 8 x 5 x 97 x 421 = 140479280

Therefore, the lowest common multiple of 688,430,194,842 is 140479280.

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.

688 x 430 x 194 x 842 = 48324872320

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

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

194 : 1, 2, 97, 194

842 : 1, 2, 421, 842

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,430,194,842, is 2.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

430:2x 5x 43

194:2x 97

842:2x 421

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 43 = 172

Therefore, the value for common factors is 172.

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 = 48324872320/(2x172)

LCM = 48324872320/344

LCM = 140479280

Thus, we can understand that the LCM of 688,430,194,842 is 140479280.
