Calculate the LCM of 341,542,403,640

Given numbers are 341,542,403,640

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

The LCM of 341,542,403,640 is 768859520.

Find LCM of 341,542,403,640 with Prime Factorization


2 341, 542, 403, 640
31 341, 271, 403, 320
11, 271, 13, 320

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

2 x 31 x 11 x 271 x 13 x 320 = 768859520

Therefore, the lowest common multiple of 341,542,403,640 is 768859520.

LCM Formula to Find Lowest Common Multiple of 341,542,403,640

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.

341 x 542 x 403 x 640 = 47669290240

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.

341 : 1, 11, 31, 341

542 : 1, 2, 271, 542

403 : 1, 13, 31, 403

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 341,542,403,640, is 1.

Now, the common factors can be found like this.

341:11x 31

542:2x 271

403:13x 31

640:2x 2x 2x 2x 2x 2x 2x 5

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 47669290240/(1x62)

LCM = 47669290240/62

LCM = 768859520

Thus, we can understand that the LCM of 341,542,403,640 is 768859520.
