The LCM of 380,940,611,731 is 169723580.

Find LCM of 380,940,611,731 with Prime Factorization


2 380, 940, 611, 731
2 190, 470, 611, 731
5 95, 235, 611, 731
47 19, 47, 611, 731
19, 1, 13, 731

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

2 x 2 x 5 x 47 x 19 x 1 x 13 x 731 = 169723580

Therefore, the lowest common multiple of 380,940,611,731 is 169723580.

LCM Formula to Find Lowest Common Multiple of 380,940,611,731

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 940 x 611 x 731 = 159540165200

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

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

611 : 1, 13, 47, 611

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,940,611,731, is 1.

Now, the common factors can be found like this.

380:2x 2x 5x 19

940:2x 2x 5x 47

611:13x 47

731:17x 43

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 5x 47 = 940

Therefore, the value for common factors is 940.

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 = 159540165200/(1x940)

LCM = 159540165200/940

LCM = 169723580

Thus, we can understand that the LCM of 380,940,611,731 is 169723580.
