Calculate the LCM of 961,947,914,768

Given numbers are 961,947,914,768

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

The LCM of 961,947,914,768 is 319411675392.

Find LCM of 961,947,914,768 with Prime Factorization


2 961, 947, 914, 768
961, 947, 457, 384

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

2 x 961 x 947 x 457 x 384 = 319411675392

Therefore, the lowest common multiple of 961,947,914,768 is 319411675392.

LCM Formula to Find Lowest Common Multiple of 961,947,914,768

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.

961 x 947 x 914 x 768 = 638823350784

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.

961 : 1, 31, 961

947 : 1, 947

914 : 1, 2, 457, 914

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,947,914,768, is 1.

Now, the common factors can be found like this.

961:31x 31

947:947

914:2x 457

768:2x 2x 2x 2x 2x 2x 2x 2x 3

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

2 = 2

Therefore, the value for common factors is 2.

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 = 638823350784/(1x2)

LCM = 638823350784/2

LCM = 319411675392

Thus, we can understand that the LCM of 961,947,914,768 is 319411675392.
