Calculate the LCM of 689,742,859,948

Given numbers are 689,742,859,948

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

The LCM of 689,742,859,948 is 3927523236.

Find LCM of 689,742,859,948 with Prime Factorization


2 689, 742, 859, 948
53 689, 371, 859, 474
13, 7, 859, 474

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

2 x 53 x 13 x 7 x 859 x 474 = 3927523236

Therefore, the lowest common multiple of 689,742,859,948 is 3927523236.

LCM Formula to Find Lowest Common Multiple of 689,742,859,948

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.

689 x 742 x 859 x 948 = 416317463016

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.

689 : 1, 13, 53, 689

742 : 1, 2, 7, 14, 53, 106, 371, 742

859 : 1, 859

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,742,859,948, is 1.

Now, the common factors can be found like this.

689:13x 53

742:2x 7x 53

859:859

948:2x 2x 3x 79

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 416317463016/(1x106)

LCM = 416317463016/106

LCM = 3927523236

Thus, we can understand that the LCM of 689,742,859,948 is 3927523236.
