The LCM of 945,867,770,758 is 2277149490.
Find LCM of 945,867,770,758 with Prime Factorization
| 2 | 945, 867, 770, 758 |
| 3 | 945, 867, 385, 379 |
| 5 | 315, 289, 385, 379 |
| 7 | 63, 289, 77, 379 |
| 9, 289, 11, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 9 x 289 x 11 x 379 = 2277149490
Therefore, the lowest common multiple of 945,867,770,758 is 2277149490.
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.
945 x 867 x 770 x 758 = 478201392900
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
867 : 1, 3, 17, 51, 289, 867
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,867,770,758, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
867:3x 17x 17
770:2x 5x 7x 11
758:2x 379
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 = 478201392900/(1x210)
LCM = 478201392900/210
LCM = 2277149490
Thus, we can understand that the LCM of 945,867,770,758 is 2277149490.
