Calculate the LCM of 355,642,145,997

Given numbers are 355,642,145,997

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

The LCM of 355,642,145,997 is 6589561830.

Find LCM of 355,642,145,997 with Prime Factorization


5 355, 642, 145, 997
71, 642, 29, 997

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

5 x 71 x 642 x 29 x 997 = 6589561830

Therefore, the lowest common multiple of 355,642,145,997 is 6589561830.

LCM Formula to Find Lowest Common Multiple of 355,642,145,997

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.

355 x 642 x 145 x 997 = 32947809150

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.

355 : 1, 5, 71, 355

642 : 1, 2, 3, 6, 107, 214, 321, 642

145 : 1, 5, 29, 145

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,642,145,997, is 1.

Now, the common factors can be found like this.

355:5x 71

642:2x 3x 107

145:5x 29

997:997

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

5 = 5

Therefore, the value for common factors is 5.

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 = 32947809150/(1x5)

LCM = 32947809150/5

LCM = 6589561830

Thus, we can understand that the LCM of 355,642,145,997 is 6589561830.
