Given numbers are 678,421,454,650

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

The LCM of 678,421,454,650 is 21058188450.

Find LCM of 678,421,454,650 with Prime Factorization

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

2 x 339 x 421 x 227 x 325 = 21058188450

Therefore, the lowest common multiple of 678,421,454,650 is 21058188450.

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.

678 x 421 x 454 x 650 = 84232753800

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

421 : 1, 421

454 : 1, 2, 227, 454

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,421,454,650, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

421:421

454:2x 227

650:2x 5x 5x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 84232753800/(1x4)

LCM = 84232753800/4

LCM = 21058188450

Thus, we can understand that the LCM of 678,421,454,650 is 21058188450.
