Calculate the LCM of 343,196,335,721

Given numbers are 343,196,335,721

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

The LCM of 343,196,335,721 is 47340860.

Find LCM of 343,196,335,721 with Prime Factorization


7 343, 196, 335, 721
7 49, 28, 335, 103
7, 4, 335, 103

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

7 x 7 x 7 x 4 x 335 x 103 = 47340860

Therefore, the lowest common multiple of 343,196,335,721 is 47340860.

LCM Formula to Find Lowest Common Multiple of 343,196,335,721

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.

343 x 196 x 335 x 721 = 16237914980

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.

343 : 1, 7, 49, 343

196 : 1, 2, 4, 7, 14, 28, 49, 98, 196

335 : 1, 5, 67, 335

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,196,335,721, is 1.

Now, the common factors can be found like this.

343:7x 7x 7

196:2x 2x 7x 7

335:5x 67

721:7x 103

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

7x 7x 7 = 343

Therefore, the value for common factors is 343.

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 = 16237914980/(1x343)

LCM = 16237914980/343

LCM = 47340860

Thus, we can understand that the LCM of 343,196,335,721 is 47340860.
