Given numbers are 136,142,429,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 136,142,429,872 is 451524216.
Find LCM of 136,142,429,872 with Prime Factorization
| 2 | 136, 142, 429, 872 |
| 2 | 68, 71, 429, 436 |
| 2 | 34, 71, 429, 218 |
| 17, 71, 429, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 71 x 429 x 109 = 451524216
Therefore, the lowest common multiple of 136,142,429,872 is 451524216.
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.
136 x 142 x 429 x 872 = 7224387456
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
142 : 1, 2, 71, 142
429 : 1, 3, 11, 13, 33, 39, 143, 429
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,142,429,872, is 1.
Now, the common factors can be found like this.
136:2x 2x 2x 17
142:2x 71
429:3x 11x 13
872:2x 2x 2x 109
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 2 = 16
Therefore, the value for common factors is 16.
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 = 7224387456/(1x16)
LCM = 7224387456/16
LCM = 451524216
Thus, we can understand that the LCM of 136,142,429,872 is 451524216.
