Given numbers are 647,221,102,479

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

The LCM of 647,221,102,479 is 410944638.

Find LCM of 647,221,102,479 with Prime Factorization

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

17 x 647 x 13 x 6 x 479 = 410944638

Therefore, the lowest common multiple of 647,221,102,479 is 410944638.

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.

647 x 221 x 102 x 479 = 6986058846

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.

647 : 1, 647

221 : 1, 13, 17, 221

102 : 1, 2, 3, 6, 17, 34, 51, 102

479 : 1, 479

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,221,102,479, is 1.

Now, the common factors can be found like this.

647:647

221:13x 17

102:2x 3x 17

479:479

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

17 = 17

Therefore, the value for common factors is 17.

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 = 6986058846/(1x17)

LCM = 6986058846/17

LCM = 410944638

Thus, we can understand that the LCM of 647,221,102,479 is 410944638.
