Calculate the LCM of 679,642,858,636

Given numbers are 679,642,858,636

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

The LCM of 679,642,858,636 is 6607645044.

Find LCM of 679,642,858,636 with Prime Factorization


2 679, 642, 858, 636
3 679, 321, 429, 318
679, 107, 143, 106

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

2 x 3 x 679 x 107 x 143 x 106 = 6607645044

Therefore, the lowest common multiple of 679,642,858,636 is 6607645044.

LCM Formula to Find Lowest Common Multiple of 679,642,858,636

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.

679 x 642 x 858 x 636 = 237875221584

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.

679 : 1, 7, 97, 679

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

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,642,858,636, is 1.

Now, the common factors can be found like this.

679:7x 97

642:2x 3x 107

858:2x 3x 11x 13

636:2x 2x 3x 53

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 237875221584/(1x36)

LCM = 237875221584/36

LCM = 6607645044

Thus, we can understand that the LCM of 679,642,858,636 is 6607645044.
