Find LCM of 238,391,716,896,442 with Prime Factorization


2 238, 391, 716, 896, 442
2 119, 391, 358, 448, 221
7 119, 391, 179, 224, 221
17 17, 391, 179, 32, 221
1, 23, 179, 32, 13

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

2 x 2 x 7 x 17 x 1 x 23 x 179 x 32 x 13 = 815231872

Therefore, the lowest common multiple of 238,391,716,896,442 is 815231872.

LCM Formula to Find Lowest Common Multiple of 238,391,716,896,442

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 391 x 716 x 896 x 442 = 26387425232896

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

391 : 1, 17, 23, 391

716 : 1, 2, 4, 179, 358, 716

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,391,716,896,442, is 1.

Now, the common factors can be found like this.

238:2x 7x 17

391:17x 23

716:2x 2x 179

896:2x 2x 2x 2x 2x 2x 2x 7

442:2x 13x 17

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 2x 2x 7x 17x 17 = 32368

Therefore, the value for common factors is 32368.

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 = 26387425232896/(1x32368)

LCM = 26387425232896/32368

LCM = 815231872

Thus, we can understand that the LCM of 238,391,716,896,442 is 815231872.
