Find LCM of 273,780,646,803,515 with Prime Factorization
| 2 | 273, 780, 646, 803, 515 |
| 3 | 273, 390, 323, 803, 515 |
| 5 | 91, 130, 323, 803, 515 |
| 13 | 91, 26, 323, 803, 103 |
| 7, 2, 323, 803, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 7 x 2 x 323 x 803 x 103 = 145863938220
Therefore, the lowest common multiple of 273,780,646,803,515 is 145863938220.
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.
273 x 780 x 646 x 803 x 515 = 56886935905800
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
646 : 1, 2, 17, 19, 34, 38, 323, 646
803 : 1, 11, 73, 803
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,780,646,803,515, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
780:2x 2x 3x 5x 13
646:2x 17x 19
803:11x 73
515:5x 103
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 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 56886935905800/(1x390)
LCM = 56886935905800/390
LCM = 145863938220
Thus, we can understand that the LCM of 273,780,646,803,515 is 145863938220.
