Calculate the LCM of 311,451,782,989,684

Given numbers are 311,451,782,989,684

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

The LCM of 311,451,782,989,684 is 1613014404012.

Find LCM of 311,451,782,989,684 with Prime Factorization


2 311, 451, 782, 989, 684
23 311, 451, 391, 989, 342
311, 451, 17, 43, 342

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

2 x 23 x 311 x 451 x 17 x 43 x 342 = 1613014404012

Therefore, the lowest common multiple of 311,451,782,989,684 is 1613014404012.

LCM Formula to Find Lowest Common Multiple of 311,451,782,989,684

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.

311 x 451 x 782 x 989 x 684 = 74198662584552

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.

311 : 1, 311

451 : 1, 11, 41, 451

782 : 1, 2, 17, 23, 34, 46, 391, 782

989 : 1, 23, 43, 989

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,451,782,989,684, is 1.

Now, the common factors can be found like this.

311:311

451:11x 41

782:2x 17x 23

989:23x 43

684:2x 2x 3x 3x 19

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 74198662584552/(1x46)

LCM = 74198662584552/46

LCM = 1613014404012

Thus, we can understand that the LCM of 311,451,782,989,684 is 1613014404012.
