Calculate the LCM of 380,859,560,691

Given numbers are 380,859,560,691

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

The LCM of 380,859,560,691 is 6315574160.

Find LCM of 380,859,560,691 with Prime Factorization


2 380, 859, 560, 691
2 190, 859, 280, 691
5 95, 859, 140, 691
19, 859, 28, 691

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

2 x 2 x 5 x 19 x 859 x 28 x 691 = 6315574160

Therefore, the lowest common multiple of 380,859,560,691 is 6315574160.

LCM Formula to Find Lowest Common Multiple of 380,859,560,691

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.

380 x 859 x 560 x 691 = 126311483200

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.

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

859 : 1, 859

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,859,560,691, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

859:859

560:2x 2x 2x 2x 5x 7

691:691

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 126311483200/(1x20)

LCM = 126311483200/20

LCM = 6315574160

Thus, we can understand that the LCM of 380,859,560,691 is 6315574160.
