Find LCM of 426,471,442,338,221 with Prime Factorization
2 | 426, 471, 442, 338, 221 |
3 | 213, 471, 221, 169, 221 |
13 | 71, 157, 221, 169, 221 |
17 | 71, 157, 17, 13, 17 |
71, 157, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 71 x 157 x 1 x 13 x 1 = 192151986
Therefore, the lowest common multiple of 426,471,442,338,221 is 192151986.
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.
426 x 471 x 442 x 338 x 221 = 6624631869336
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
471 : 1, 3, 157, 471
442 : 1, 2, 13, 17, 26, 34, 221, 442
338 : 1, 2, 13, 26, 169, 338
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,471,442,338,221, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
471:3x 157
442:2x 13x 17
338:2x 13x 13
221:13x 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 3x 13x 13x 17 = 34476
Therefore, the value for common factors is 34476.
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 = 6624631869336/(1x34476)
LCM = 6624631869336/34476
LCM = 192151986
Thus, we can understand that the LCM of 426,471,442,338,221 is 192151986.
