Given numbers are 430,921,770

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

The LCM of 430,921,770 is 30494310.

Find LCM of 430,921,770 with Prime Factorization

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

2 x 5 x 43 x 921 x 77 = 30494310

Therefore, the lowest common multiple of 430,921,770 is 30494310.

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.

430 x 921 x 770 = 304943100

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.

430 : 1, 2, 5, 10, 43, 86, 215, 430

921 : 1, 3, 307, 921

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,921,770, is 1.

Now, the common factors can be found like this.

430:2x 5x 43

921:3x 307

770:2x 5x 7x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 304943100/(1x10)

LCM = 304943100/10

LCM = 30494310

Thus, we can understand that the LCM of 430,921,770 is 30494310.
