Find LCM of 247,798,684,730,444 with Prime Factorization
| 2 | 247, 798, 684, 730, 444 |
| 2 | 247, 399, 342, 365, 222 |
| 3 | 247, 399, 171, 365, 111 |
| 19 | 247, 133, 57, 365, 37 |
| 13, 7, 3, 365, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 13 x 7 x 3 x 365 x 37 = 840605220
Therefore, the lowest common multiple of 247,798,684,730,444 is 840605220.
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.
247 x 798 x 684 x 730 x 444 = 43698021756480
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.
247 : 1, 13, 19, 247
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
730 : 1, 2, 5, 10, 73, 146, 365, 730
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,798,684,730,444, is 1.
Now, the common factors can be found like this.
247:13x 19
798:2x 3x 7x 19
684:2x 2x 3x 3x 19
730:2x 5x 73
444:2x 2x 3x 37
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 2x 3x 3x 19x 19 = 51984
Therefore, the value for common factors is 51984.
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 = 43698021756480/(1x51984)
LCM = 43698021756480/51984
LCM = 840605220
Thus, we can understand that the LCM of 247,798,684,730,444 is 840605220.
