Given numbers are 919,817,919,721

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

The LCM of 919,817,919,721 is 541343383.

Find LCM of 919,817,919,721 with Prime Factorization

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

919 x 1 x 817 x 1 x 721 = 541343383

Therefore, the lowest common multiple of 919,817,919,721 is 541343383.

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.

919 x 817 x 919 x 721 = 497494568977

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.

919 : 1, 919

817 : 1, 19, 43, 817

919 : 1, 919

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,817,919,721, is 1.

Now, the common factors can be found like this.

919:919

817:19x 43

919:919

721:7x 103

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

919 = 919

Therefore, the value for common factors is 919.

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 = 497494568977/(1x919)

LCM = 497494568977/919

LCM = 541343383

Thus, we can understand that the LCM of 919,817,919,721 is 541343383.
