Given numbers are 347,516,821,642

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

The LCM of 347,516,821,642 is 15729181044.

Find LCM of 347,516,821,642 with Prime Factorization

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

2 x 3 x 347 x 86 x 821 x 107 = 15729181044

Therefore, the lowest common multiple of 347,516,821,642 is 15729181044.

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.

347 x 516 x 821 x 642 = 94375086264

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.

347 : 1, 347

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

821 : 1, 821

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,516,821,642, is 1.

Now, the common factors can be found like this.

347:347

516:2x 2x 3x 43

821:821

642:2x 3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 94375086264/(1x6)

LCM = 94375086264/6

LCM = 15729181044

Thus, we can understand that the LCM of 347,516,821,642 is 15729181044.
