Given numbers are 781,764,642,624

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

The LCM of 781,764,642,624 is 9959849328.

Find LCM of 781,764,642,624 with Prime Factorization

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

2 x 2 x 3 x 781 x 191 x 107 x 52 = 9959849328

Therefore, the lowest common multiple of 781,764,642,624 is 9959849328.

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.

781 x 764 x 642 x 624 = 239036383872

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.

781 : 1, 11, 71, 781

764 : 1, 2, 4, 191, 382, 764

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

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,764,642,624, is 1.

Now, the common factors can be found like this.

781:11x 71

764:2x 2x 191

642:2x 3x 107

624:2x 2x 2x 2x 3x 13

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 3 = 24

Therefore, the value for common factors is 24.

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 = 239036383872/(1x24)

LCM = 239036383872/24

LCM = 9959849328

Thus, we can understand that the LCM of 781,764,642,624 is 9959849328.
