Calculate the LCM of 982,437,390,345

Given numbers are 982,437,390,345

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

The LCM of 982,437,390,345 is 83681130.

Find LCM of 982,437,390,345 with Prime Factorization


2 982, 437, 390, 345
3 491, 437, 195, 345
5 491, 437, 65, 115
23 491, 437, 13, 23
491, 19, 13, 1

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

2 x 3 x 5 x 23 x 491 x 19 x 13 x 1 = 83681130

Therefore, the lowest common multiple of 982,437,390,345 is 83681130.

LCM Formula to Find Lowest Common Multiple of 982,437,390,345

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.

982 x 437 x 390 x 345 = 57739979700

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.

982 : 1, 2, 491, 982

437 : 1, 19, 23, 437

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

345 : 1, 3, 5, 15, 23, 69, 115, 345

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 982,437,390,345, is 1.

Now, the common factors can be found like this.

982:2x 491

437:19x 23

390:2x 3x 5x 13

345:3x 5x 23

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

2x 3x 5x 23 = 690

Therefore, the value for common factors is 690.

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 = 57739979700/(1x690)

LCM = 57739979700/690

LCM = 83681130

Thus, we can understand that the LCM of 982,437,390,345 is 83681130.
