Find LCM of 955,912,394,720 with Prime Factorization
| 2 | 955, 912, 394, 720 |
| 2 | 955, 456, 197, 360 |
| 2 | 955, 228, 197, 180 |
| 2 | 955, 114, 197, 90 |
| 3 | 955, 57, 197, 45 |
| 5 | 955, 19, 197, 15 |
| 191, 19, 197, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 191 x 19 x 197 x 3 = 514737360
Therefore, the lowest common multiple of 955,912,394,720 is 514737360.
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.
955 x 912 x 394 x 720 = 247073932800
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.
955 : 1, 5, 191, 955
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
394 : 1, 2, 197, 394
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,912,394,720, is 1.
Now, the common factors can be found like this.
955:5x 191
912:2x 2x 2x 2x 3x 19
394:2x 197
720:2x 2x 2x 2x 3x 3x 5
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 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 247073932800/(1x480)
LCM = 247073932800/480
LCM = 514737360
Thus, we can understand that the LCM of 955,912,394,720 is 514737360.
