Calculate the LCM of 687,343,188,830,141

Given numbers are 687,343,188,830,141

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

The LCM of 687,343,188,830,141 is 18384710820.

Find LCM of 687,343,188,830,141 with Prime Factorization


2 687, 343, 188, 830, 141
3 687, 343, 94, 415, 141
47 229, 343, 94, 415, 47
229, 343, 2, 415, 1

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

2 x 3 x 47 x 229 x 343 x 2 x 415 x 1 = 18384710820

Therefore, the lowest common multiple of 687,343,188,830,141 is 18384710820.

LCM Formula to Find Lowest Common Multiple of 687,343,188,830,141

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.

687 x 343 x 188 x 830 x 141 = 5184488451240

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.

687 : 1, 3, 229, 687

343 : 1, 7, 49, 343

188 : 1, 2, 4, 47, 94, 188

830 : 1, 2, 5, 10, 83, 166, 415, 830

141 : 1, 3, 47, 141

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,343,188,830,141, is 1.

Now, the common factors can be found like this.

687:3x 229

343:7x 7x 7

188:2x 2x 47

830:2x 5x 83

141:3x 47

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

2x 3x 47 = 282

Therefore, the value for common factors is 282.

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 = 5184488451240/(1x282)

LCM = 5184488451240/282

LCM = 18384710820

Thus, we can understand that the LCM of 687,343,188,830,141 is 18384710820.
