Calculate the LCM of 391,514,832,462

Given numbers are 391,514,832,462

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

The LCM of 391,514,832,462 is 19312797504.

Find LCM of 391,514,832,462 with Prime Factorization


2 391, 514, 832, 462
391, 257, 416, 231

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

2 x 391 x 257 x 416 x 231 = 19312797504

Therefore, the lowest common multiple of 391,514,832,462 is 19312797504.

LCM Formula to Find Lowest Common Multiple of 391,514,832,462

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.

391 x 514 x 832 x 462 = 77251190016

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.

391 : 1, 17, 23, 391

514 : 1, 2, 257, 514

832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,514,832,462, is 1.

Now, the common factors can be found like this.

391:17x 23

514:2x 257

832:2x 2x 2x 2x 2x 2x 13

462:2x 3x 7x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 77251190016/(1x4)

LCM = 77251190016/4

LCM = 19312797504

Thus, we can understand that the LCM of 391,514,832,462 is 19312797504.
