Find LCM of 882,915,455,946 with Prime Factorization
| 2 | 882, 915, 455, 946 |
| 3 | 441, 915, 455, 473 |
| 5 | 147, 305, 455, 473 |
| 7 | 147, 61, 91, 473 |
| 21, 61, 13, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 21 x 61 x 13 x 473 = 1654142490
Therefore, the lowest common multiple of 882,915,455,946 is 1654142490.
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.
882 x 915 x 455 x 946 = 347369922900
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
915 : 1, 3, 5, 15, 61, 183, 305, 915
455 : 1, 5, 7, 13, 35, 65, 91, 455
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,915,455,946, is 1.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
915:3x 5x 61
455:5x 7x 13
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 347369922900/(1x210)
LCM = 347369922900/210
LCM = 1654142490
Thus, we can understand that the LCM of 882,915,455,946 is 1654142490.
