Given numbers are 428,642,842,679

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

The LCM of 428,642,842,679 is 367042956.

Find LCM of 428,642,842,679 with Prime Factorization

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

2 x 107 x 2 x 3 x 421 x 679 = 367042956

Therefore, the lowest common multiple of 428,642,842,679 is 367042956.

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.

428 x 642 x 842 x 679 = 157094385168

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.

428 : 1, 2, 4, 107, 214, 428

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

842 : 1, 2, 421, 842

679 : 1, 7, 97, 679

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,642,842,679, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

642:2x 3x 107

842:2x 421

679:7x 97

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 107 = 428

Therefore, the value for common factors is 428.

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 = 157094385168/(1x428)

LCM = 157094385168/428

LCM = 367042956

Thus, we can understand that the LCM of 428,642,842,679 is 367042956.
