Find LCM of 390,861,294,528,944 with Prime Factorization
| 2 | 390, 861, 294, 528, 944 |
| 2 | 195, 861, 147, 264, 472 |
| 2 | 195, 861, 147, 132, 236 |
| 2 | 195, 861, 147, 66, 118 |
| 3 | 195, 861, 147, 33, 59 |
| 7 | 65, 287, 49, 11, 59 |
| 65, 41, 7, 11, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 65 x 41 x 7 x 11 x 59 = 4067983920
Therefore, the lowest common multiple of 390,861,294,528,944 is 4067983920.
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 861 x 294 x 528 x 944 = 49206333496320
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,861,294,528,944, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
861:3x 7x 41
294:2x 3x 7x 7
528:2x 2x 2x 2x 3x 11
944:2x 2x 2x 2x 59
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 2x 2x 3x 3x 3x 7 = 12096
Therefore, the value for common factors is 12096.
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 = 49206333496320/(1x12096)
LCM = 49206333496320/12096
LCM = 4067983920
Thus, we can understand that the LCM of 390,861,294,528,944 is 4067983920.
