Calculate the LCM of 381,638,190,627

Given numbers are 381,638,190,627

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

The LCM of 381,638,190,627 is 23092410.

Find LCM of 381,638,190,627 with Prime Factorization


2 381, 638, 190, 627
3 381, 319, 95, 627
11 127, 319, 95, 209
19 127, 29, 95, 19
127, 29, 5, 1

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

2 x 3 x 11 x 19 x 127 x 29 x 5 x 1 = 23092410

Therefore, the lowest common multiple of 381,638,190,627 is 23092410.

LCM Formula to Find Lowest Common Multiple of 381,638,190,627

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.

381 x 638 x 190 x 627 = 28957882140

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.

381 : 1, 3, 127, 381

638 : 1, 2, 11, 22, 29, 58, 319, 638

190 : 1, 2, 5, 10, 19, 38, 95, 190

627 : 1, 3, 11, 19, 33, 57, 209, 627

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,638,190,627, is 1.

Now, the common factors can be found like this.

381:3x 127

638:2x 11x 29

190:2x 5x 19

627:3x 11x 19

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

2x 3x 11x 19 = 1254

Therefore, the value for common factors is 1254.

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 = 28957882140/(1x1254)

LCM = 28957882140/1254

LCM = 23092410

Thus, we can understand that the LCM of 381,638,190,627 is 23092410.
