Find LCM of 768,422,507,156,338 with Prime Factorization
| 2 | 768, 422, 507, 156, 338 |
| 2 | 384, 211, 507, 78, 169 |
| 3 | 192, 211, 507, 39, 169 |
| 13 | 64, 211, 169, 13, 169 |
| 13 | 64, 211, 1, 13, 13 |
| 64, 211, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 13 x 64 x 211 x 1 x 1 x 1 = 27386112
Therefore, the lowest common multiple of 768,422,507,156,338 is 27386112.
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.
768 x 422 x 507 x 156 x 338 = 8664089481216
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
422 : 1, 2, 211, 422
507 : 1, 3, 13, 39, 169, 507
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,422,507,156,338, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
422:2x 211
507:3x 13x 13
156:2x 2x 3x 13
338:2x 13x 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 2x 2x 3x 3x 13x 13x 13 = 316368
Therefore, the value for common factors is 316368.
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 = 8664089481216/(1x316368)
LCM = 8664089481216/316368
LCM = 27386112
Thus, we can understand that the LCM of 768,422,507,156,338 is 27386112.
