Calculate the LCM of 238,998,490,650

Given numbers are 238,998,490,650

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

The LCM of 238,998,490,650 is 270183550.

Find LCM of 238,998,490,650 with Prime Factorization


2 238, 998, 490, 650
5 119, 499, 245, 325
7 119, 499, 49, 65
17, 499, 7, 65

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

2 x 5 x 7 x 17 x 499 x 7 x 65 = 270183550

Therefore, the lowest common multiple of 238,998,490,650 is 270183550.

LCM Formula to Find Lowest Common Multiple of 238,998,490,650

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.

238 x 998 x 490 x 650 = 75651394000

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.

238 : 1, 2, 7, 14, 17, 34, 119, 238

998 : 1, 2, 499, 998

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,998,490,650, is 2.

Now, the common factors can be found like this.

238:2x 7x 17

998:2x 499

490:2x 5x 7x 7

650:2x 5x 5x 13

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 5x 7 = 140

Therefore, the value for common factors is 140.

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 = 75651394000/(2x140)

LCM = 75651394000/280

LCM = 270183550

Thus, we can understand that the LCM of 238,998,490,650 is 270183550.
