Given numbers are 619,121,408,672

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

The LCM of 619,121,408,672 is 855646176.

Find LCM of 619,121,408,672 with Prime Factorization

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

2 x 2 x 2 x 3 x 619 x 121 x 17 x 28 = 855646176

Therefore, the lowest common multiple of 619,121,408,672 is 855646176.

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.

619 x 121 x 408 x 672 = 20535508224

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.

619 : 1, 619

121 : 1, 11, 121

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,121,408,672, is 1.

Now, the common factors can be found like this.

619:619

121:11x 11

408:2x 2x 2x 3x 17

672:2x 2x 2x 2x 2x 3x 7

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 = 20535508224/(1x24)

LCM = 20535508224/24

LCM = 855646176

Thus, we can understand that the LCM of 619,121,408,672 is 855646176.
