Find LCM of 704,416,832,326,978 with Prime Factorization
| 2 | 704, 416, 832, 326, 978 |
| 2 | 352, 208, 416, 163, 489 |
| 2 | 176, 104, 208, 163, 489 |
| 2 | 88, 52, 104, 163, 489 |
| 2 | 44, 26, 52, 163, 489 |
| 2 | 22, 13, 26, 163, 489 |
| 13 | 11, 13, 13, 163, 489 |
| 163 | 11, 1, 1, 163, 489 |
| 11, 1, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 13 x 163 x 11 x 1 x 1 x 1 x 3 = 4475328
Therefore, the lowest common multiple of 704,416,832,326,978 is 4475328.
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.
704 x 416 x 832 x 326 x 978 = 77686538502144
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
326 : 1, 2, 163, 326
978 : 1, 2, 3, 6, 163, 326, 489, 978
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,416,832,326,978, is 2.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
416:2x 2x 2x 2x 2x 13
832:2x 2x 2x 2x 2x 2x 13
326:2x 163
978:2x 3x 163
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 2x 2x 2x 2x 2x 2x 13x 163 = 8679424
Therefore, the value for common factors is 8679424.
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 = 77686538502144/(2x8679424)
LCM = 77686538502144/17358848
LCM = 4475328
Thus, we can understand that the LCM of 704,416,832,326,978 is 4475328.
