Calculate the LCM of 312,515,438,786

Given numbers are 312,515,438,786

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

The LCM of 312,515,438,786 is 1536582840.

Find LCM of 312,515,438,786 with Prime Factorization


2 312, 515, 438, 786
3 156, 515, 219, 393
52, 515, 73, 131

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

2 x 3 x 52 x 515 x 73 x 131 = 1536582840

Therefore, the lowest common multiple of 312,515,438,786 is 1536582840.

LCM Formula to Find Lowest Common Multiple of 312,515,438,786

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.

312 x 515 x 438 x 786 = 55316982240

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.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

515 : 1, 5, 103, 515

438 : 1, 2, 3, 6, 73, 146, 219, 438

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,515,438,786, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

515:5x 103

438:2x 3x 73

786:2x 3x 131

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 55316982240/(1x36)

LCM = 55316982240/36

LCM = 1536582840

Thus, we can understand that the LCM of 312,515,438,786 is 1536582840.
