Given numbers are 133,495,617,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 133,495,617,770 is 81240390.
Find LCM of 133,495,617,770 with Prime Factorization
| 5 | 133, 495, 617, 770 |
| 7 | 133, 99, 617, 154 |
| 11 | 19, 99, 617, 22 |
| 19, 9, 617, 2 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 19 x 9 x 617 x 2 = 81240390
Therefore, the lowest common multiple of 133,495,617,770 is 81240390.
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.
133 x 495 x 617 x 770 = 31277550150
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.
133 : 1, 7, 19, 133
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
617 : 1, 617
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 133,495,617,770, is 1.
Now, the common factors can be found like this.
133:7x 19
495:3x 3x 5x 11
617:617
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11 = 385
Therefore, the value for common factors is 385.
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 = 31277550150/(1x385)
LCM = 31277550150/385
LCM = 81240390
Thus, we can understand that the LCM of 133,495,617,770 is 81240390.
