Find LCM of 277,288,957,445,780 with Prime Factorization
| 2 | 277, 288, 957, 445, 780 |
| 2 | 277, 144, 957, 445, 390 |
| 3 | 277, 72, 957, 445, 195 |
| 5 | 277, 24, 319, 445, 65 |
| 277, 24, 319, 89, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 277 x 24 x 319 x 89 x 13 = 147219827040
Therefore, the lowest common multiple of 277,288,957,445,780 is 147219827040.
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.
277 x 288 x 957 x 445 x 780 = 26499568867200
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.
277 : 1, 277
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
957 : 1, 3, 11, 29, 33, 87, 319, 957
445 : 1, 5, 89, 445
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,288,957,445,780, is 1.
Now, the common factors can be found like this.
277:277
288:2x 2x 2x 2x 2x 3x 3
957:3x 11x 29
445:5x 89
780:2x 2x 3x 5x 13
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 26499568867200/(1x180)
LCM = 26499568867200/180
LCM = 147219827040
Thus, we can understand that the LCM of 277,288,957,445,780 is 147219827040.
