Given numbers are 672,840,454,326

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

The LCM of 672,840,454,326 is 124323360.

Find LCM of 672,840,454,326 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 4 x 5 x 227 x 163 = 124323360

Therefore, the lowest common multiple of 672,840,454,326 is 124323360.

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.

672 x 840 x 454 x 326 = 83545297920

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.

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

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

454 : 1, 2, 227, 454

326 : 1, 2, 163, 326

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,840,454,326, is 2.

Now, the common factors can be found like this.

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

840:2x 2x 2x 3x 5x 7

454:2x 227

326:2x 163

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 2x 3x 7 = 336

Therefore, the value for common factors is 336.

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 = 83545297920/(2x336)

LCM = 83545297920/672

LCM = 124323360

Thus, we can understand that the LCM of 672,840,454,326 is 124323360.
