Calculate the LCM of 155,381,863,862,505

Given numbers are 155,381,863,862,505

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

The LCM of 155,381,863,862,505 is 4437068251830.

Find LCM of 155,381,863,862,505 with Prime Factorization


5 155, 381, 863, 862, 505
31, 381, 863, 862, 101

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

5 x 31 x 381 x 863 x 862 x 101 = 4437068251830

Therefore, the lowest common multiple of 155,381,863,862,505 is 4437068251830.

LCM Formula to Find Lowest Common Multiple of 155,381,863,862,505

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.

155 x 381 x 863 x 862 x 505 = 22185341259150

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.

155 : 1, 5, 31, 155

381 : 1, 3, 127, 381

863 : 1, 863

862 : 1, 2, 431, 862

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,381,863,862,505, is 1.

Now, the common factors can be found like this.

155:5x 31

381:3x 127

863:863

862:2x 431

505:5x 101

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

5 = 5

Therefore, the value for common factors is 5.

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 = 22185341259150/(1x5)

LCM = 22185341259150/5

LCM = 4437068251830

Thus, we can understand that the LCM of 155,381,863,862,505 is 4437068251830.
