Calculate the LCM of 661,914,745,432

Given numbers are 661,914,745,432

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

The LCM of 661,914,745,432 is 97220461680.

Find LCM of 661,914,745,432 with Prime Factorization


2 661, 914, 745, 432
661, 457, 745, 216

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

2 x 661 x 457 x 745 x 216 = 97220461680

Therefore, the lowest common multiple of 661,914,745,432 is 97220461680.

LCM Formula to Find Lowest Common Multiple of 661,914,745,432

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.

661 x 914 x 745 x 432 = 194440923360

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.

661 : 1, 661

914 : 1, 2, 457, 914

745 : 1, 5, 149, 745

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,914,745,432, is 1.

Now, the common factors can be found like this.

661:661

914:2x 457

745:5x 149

432:2x 2x 2x 2x 3x 3x 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 = 194440923360/(1x2)

LCM = 194440923360/2

LCM = 97220461680

Thus, we can understand that the LCM of 661,914,745,432 is 97220461680.
