Given numbers are 634,556,819,642,122

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

The LCM of 634,556,819,642,122 is 942174982476.

Find LCM of 634,556,819,642,122 with Prime Factorization

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

2 x 3 x 317 x 278 x 273 x 107 x 61 = 942174982476

Therefore, the lowest common multiple of 634,556,819,642,122 is 942174982476.

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.

634 x 556 x 819 x 642 x 122 = 22612199579424

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.

634 : 1, 2, 317, 634

556 : 1, 2, 4, 139, 278, 556

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,556,819,642,122, is 1.

Now, the common factors can be found like this.

634:2x 317

556:2x 2x 139

819:3x 3x 7x 13

642:2x 3x 107

122:2x 61

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 = 22612199579424/(1x24)

LCM = 22612199579424/24

LCM = 942174982476

Thus, we can understand that the LCM of 634,556,819,642,122 is 942174982476.
