Given numbers are 392,168,347,398,798

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

The LCM of 392,168,347,398,798 is 1542920232.

Find LCM of 392,168,347,398,798 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 1 x 7 x 347 x 199 x 19 = 1542920232

Therefore, the lowest common multiple of 392,168,347,398,798 is 1542920232.

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.

392 x 168 x 347 x 398 x 798 = 7257896771328

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

347 : 1, 347

398 : 1, 2, 199, 398

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,168,347,398,798, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

168:2x 2x 2x 3x 7

347:347

398:2x 199

798:2x 3x 7x 19

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 2x 2x 2x 3x 7x 7 = 4704

Therefore, the value for common factors is 4704.

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 = 7257896771328/(1x4704)

LCM = 7257896771328/4704

LCM = 1542920232

Thus, we can understand that the LCM of 392,168,347,398,798 is 1542920232.
