Given numbers are 169,429,847,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,429,847,721 is 44231187.
Find LCM of 169,429,847,721 with Prime Factorization
| 7 | 169, 429, 847, 721 |
| 11 | 169, 429, 121, 103 |
| 13 | 169, 39, 11, 103 |
| 13, 3, 11, 103 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 13 x 13 x 3 x 11 x 103 = 44231187
Therefore, the lowest common multiple of 169,429,847,721 is 44231187.
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.
169 x 429 x 847 x 721 = 44275418187
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.
169 : 1, 13, 169
429 : 1, 3, 11, 13, 33, 39, 143, 429
847 : 1, 7, 11, 77, 121, 847
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,429,847,721, is 1.
Now, the common factors can be found like this.
169:13x 13
429:3x 11x 13
847:7x 11x 11
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 13 = 1001
Therefore, the value for common factors is 1001.
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 = 44275418187/(1x1001)
LCM = 44275418187/1001
LCM = 44231187
Thus, we can understand that the LCM of 169,429,847,721 is 44231187.
