Calculate the LCM of 689,764,451,165

Given numbers are 689,764,451,165

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

The LCM of 689,764,451,165 is 3561068940.

Find LCM of 689,764,451,165 with Prime Factorization


11 689, 764, 451, 165
689, 764, 41, 15

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

11 x 689 x 764 x 41 x 15 = 3561068940

Therefore, the lowest common multiple of 689,764,451,165 is 3561068940.

LCM Formula to Find Lowest Common Multiple of 689,764,451,165

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 764 x 451 x 165 = 39171758340

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

764 : 1, 2, 4, 191, 382, 764

451 : 1, 11, 41, 451

165 : 1, 3, 5, 11, 15, 33, 55, 165

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,764,451,165, is 1.

Now, the common factors can be found like this.

689:13x 53

764:2x 2x 191

451:11x 41

165:3x 5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 39171758340/(1x11)

LCM = 39171758340/11

LCM = 3561068940

Thus, we can understand that the LCM of 689,764,451,165 is 3561068940.
