Calculate the LCM of 248,391,298,138

Given numbers are 248,391,298,138

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

The LCM of 248,391,298,138 is 43344696.

Find LCM of 248,391,298,138 with Prime Factorization


2 248, 391, 298, 138
23 124, 391, 149, 69
124, 17, 149, 3

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

2 x 23 x 124 x 17 x 149 x 3 = 43344696

Therefore, the lowest common multiple of 248,391,298,138 is 43344696.

LCM Formula to Find Lowest Common Multiple of 248,391,298,138

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.

248 x 391 x 298 x 138 = 3987712032

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.

248 : 1, 2, 4, 8, 31, 62, 124, 248

391 : 1, 17, 23, 391

298 : 1, 2, 149, 298

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,391,298,138, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

391:17x 23

298:2x 149

138:2x 3x 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 2x 23 = 92

Therefore, the value for common factors is 92.

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 = 3987712032/(1x92)

LCM = 3987712032/92

LCM = 43344696

Thus, we can understand that the LCM of 248,391,298,138 is 43344696.
