Calculate the LCM of 312,403,551,337,646

Given numbers are 312,403,551,337,646

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

The LCM of 312,403,551,337,646 is 30531399288.

Find LCM of 312,403,551,337,646 with Prime Factorization


2 312, 403, 551, 337, 646
13 156, 403, 551, 337, 323
19 12, 31, 551, 337, 323
12, 31, 29, 337, 17

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

2 x 13 x 19 x 12 x 31 x 29 x 337 x 17 = 30531399288

Therefore, the lowest common multiple of 312,403,551,337,646 is 30531399288.

LCM Formula to Find Lowest Common Multiple of 312,403,551,337,646

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 403 x 551 x 337 x 646 = 15082511248272

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

403 : 1, 13, 31, 403

551 : 1, 19, 29, 551

337 : 1, 337

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,403,551,337,646, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

403:13x 31

551:19x 29

337:337

646:2x 17x 19

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

2x 13x 19 = 494

Therefore, the value for common factors is 494.

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 = 15082511248272/(1x494)

LCM = 15082511248272/494

LCM = 30531399288

Thus, we can understand that the LCM of 312,403,551,337,646 is 30531399288.
