Calculate the LCM of 689,618,974,382

Given numbers are 689,618,974,382

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

The LCM of 689,618,974,382 is 39606824634.

Find LCM of 689,618,974,382 with Prime Factorization


2 689, 618, 974, 382
689, 309, 487, 191

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

2 x 689 x 309 x 487 x 191 = 39606824634

Therefore, the lowest common multiple of 689,618,974,382 is 39606824634.

LCM Formula to Find Lowest Common Multiple of 689,618,974,382

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 618 x 974 x 382 = 158427298536

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

618 : 1, 2, 3, 6, 103, 206, 309, 618

974 : 1, 2, 487, 974

382 : 1, 2, 191, 382

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,618,974,382, is 1.

Now, the common factors can be found like this.

689:13x 53

618:2x 3x 103

974:2x 487

382:2x 191

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 158427298536/(1x4)

LCM = 158427298536/4

LCM = 39606824634

Thus, we can understand that the LCM of 689,618,974,382 is 39606824634.
