Calculate the LCM of 615,335,205,672

Given numbers are 615,335,205,672

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

The LCM of 615,335,205,672 is 9229920.

Find LCM of 615,335,205,672 with Prime Factorization


3 615, 335, 205, 672
5 205, 335, 205, 224
41 41, 67, 41, 224
1, 67, 1, 224

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

3 x 5 x 41 x 1 x 67 x 1 x 224 = 9229920

Therefore, the lowest common multiple of 615,335,205,672 is 9229920.

LCM Formula to Find Lowest Common Multiple of 615,335,205,672

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.

615 x 335 x 205 x 672 = 28382004000

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.

615 : 1, 3, 5, 15, 41, 123, 205, 615

335 : 1, 5, 67, 335

205 : 1, 5, 41, 205

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,335,205,672, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

335:5x 67

205:5x 41

672:2x 2x 2x 2x 2x 3x 7

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

3x 5x 5x 41 = 3075

Therefore, the value for common factors is 3075.

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 = 28382004000/(1x3075)

LCM = 28382004000/3075

LCM = 9229920

Thus, we can understand that the LCM of 615,335,205,672 is 9229920.
