Given numbers are 677,219,921,730

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

The LCM of 677,219,921,730 is 455167410.

Find LCM of 677,219,921,730 with Prime Factorization

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

3 x 73 x 677 x 1 x 307 x 10 = 455167410

Therefore, the lowest common multiple of 677,219,921,730 is 455167410.

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.

677 x 219 x 921 x 730 = 99681662790

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.

677 : 1, 677

219 : 1, 3, 73, 219

921 : 1, 3, 307, 921

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,219,921,730, is 1.

Now, the common factors can be found like this.

677:677

219:3x 73

921:3x 307

730:2x 5x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 73 = 219

Therefore, the value for common factors is 219.

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 = 99681662790/(1x219)

LCM = 99681662790/219

LCM = 455167410

Thus, we can understand that the LCM of 677,219,921,730 is 455167410.
