The LCM of 390,827,708,280 is 532819560.
Find LCM of 390,827,708,280 with Prime Factorization
| 2 | 390, 827, 708, 280 |
| 2 | 195, 827, 354, 140 |
| 3 | 195, 827, 177, 70 |
| 5 | 65, 827, 59, 70 |
| 13, 827, 59, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 827 x 59 x 14 = 532819560
Therefore, the lowest common multiple of 390,827,708,280 is 532819560.
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.
390 x 827 x 708 x 280 = 63938347200
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
827 : 1, 827
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,827,708,280, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
827:827
708:2x 2x 3x 59
280:2x 2x 2x 5x 7
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 63938347200/(1x120)
LCM = 63938347200/120
LCM = 532819560
Thus, we can understand that the LCM of 390,827,708,280 is 532819560.
