Find LCM of 783,909,798,168,357 with Prime Factorization
| 2 | 783, 909, 798, 168, 357 |
| 3 | 783, 909, 399, 84, 357 |
| 3 | 261, 303, 133, 28, 119 |
| 7 | 87, 101, 133, 28, 119 |
| 87, 101, 19, 4, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 87 x 101 x 19 x 4 x 17 = 1430453304
Therefore, the lowest common multiple of 783,909,798,168,357 is 1430453304.
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.
783 x 909 x 798 x 168 x 357 = 34064814981456
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
909 : 1, 3, 9, 101, 303, 909
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
357 : 1, 3, 7, 17, 21, 51, 119, 357
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,909,798,168,357, is 3.
Now, the common factors can be found like this.
783:3x 3x 3x 29
909:3x 3x 101
798:2x 3x 7x 19
168:2x 2x 2x 3x 7
357:3x 7x 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 3x 3x 3x 3x 7x 7 = 7938
Therefore, the value for common factors is 7938.
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 = 34064814981456/(3x7938)
LCM = 34064814981456/23814
LCM = 1430453304
Thus, we can understand that the LCM of 783,909,798,168,357 is 1430453304.
