Given numbers are 847,152,960,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 847,152,960,623 is 1374985920.
Find LCM of 847,152,960,623 with Prime Factorization
| 2 | 847, 152, 960, 623 |
| 2 | 847, 76, 480, 623 |
| 2 | 847, 38, 240, 623 |
| 7 | 847, 19, 120, 623 |
| 121, 19, 120, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 121 x 19 x 120 x 89 = 1374985920
Therefore, the lowest common multiple of 847,152,960,623 is 1374985920.
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.
847 x 152 x 960 x 623 = 76999211520
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.
847 : 1, 7, 11, 77, 121, 847
152 : 1, 2, 4, 8, 19, 38, 76, 152
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,152,960,623, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
152:2x 2x 2x 19
960:2x 2x 2x 2x 2x 2x 3x 5
623:7x 89
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 7 = 56
Therefore, the value for common factors is 56.
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 = 76999211520/(1x56)
LCM = 76999211520/56
LCM = 1374985920
Thus, we can understand that the LCM of 847,152,960,623 is 1374985920.
