Given numbers are 919,154,172,781

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

The LCM of 919,154,172,781 is 864157756.

Find LCM of 919,154,172,781 with Prime Factorization

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

2 x 11 x 919 x 7 x 86 x 71 = 864157756

Therefore, the lowest common multiple of 919,154,172,781 is 864157756.

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 154 x 172 x 781 = 19011470632

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

154 : 1, 2, 7, 11, 14, 22, 77, 154

172 : 1, 2, 4, 43, 86, 172

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,154,172,781, is 1.

Now, the common factors can be found like this.

919:919

154:2x 7x 11

172:2x 2x 43

781:11x 71

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 19011470632/(1x22)

LCM = 19011470632/22

LCM = 864157756

Thus, we can understand that the LCM of 919,154,172,781 is 864157756.
