Find LCM of 555,330,979,640,378 with Prime Factorization
| 2 | 555, 330, 979, 640, 378 |
| 3 | 555, 165, 979, 320, 189 |
| 5 | 185, 55, 979, 320, 63 |
| 11 | 37, 11, 979, 64, 63 |
| 37, 1, 89, 64, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 37 x 1 x 89 x 64 x 63 = 4381534080
Therefore, the lowest common multiple of 555,330,979,640,378 is 4381534080.
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.
555 x 330 x 979 x 640 x 378 = 43377187392000
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
979 : 1, 11, 89, 979
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,330,979,640,378, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
330:2x 3x 5x 11
979:11x 89
640:2x 2x 2x 2x 2x 2x 2x 5
378:2x 3x 3x 3x 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 3x 3x 5x 5x 11 = 9900
Therefore, the value for common factors is 9900.
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 = 43377187392000/(1x9900)
LCM = 43377187392000/9900
LCM = 4381534080
Thus, we can understand that the LCM of 555,330,979,640,378 is 4381534080.
