Calculate the LCM of 331,299,989,245

Given numbers are 331,299,989,245

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

The LCM of 331,299,989,245 is 1042638415.

Find LCM of 331,299,989,245 with Prime Factorization


23 331, 299, 989, 245
331, 13, 43, 245

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

23 x 331 x 13 x 43 x 245 = 1042638415

Therefore, the lowest common multiple of 331,299,989,245 is 1042638415.

LCM Formula to Find Lowest Common Multiple of 331,299,989,245

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.

331 x 299 x 989 x 245 = 23980683545

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.

331 : 1, 331

299 : 1, 13, 23, 299

989 : 1, 23, 43, 989

245 : 1, 5, 7, 35, 49, 245

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,299,989,245, is 1.

Now, the common factors can be found like this.

331:331

299:13x 23

989:23x 43

245:5x 7x 7

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

23 = 23

Therefore, the value for common factors is 23.

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 = 23980683545/(1x23)

LCM = 23980683545/23

LCM = 1042638415

Thus, we can understand that the LCM of 331,299,989,245 is 1042638415.
