Given numbers are 102,187,847,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,187,847,992 is 42851424.
Find LCM of 102,187,847,992 with Prime Factorization
| 2 | 102, 187, 847, 992 |
| 11 | 51, 187, 847, 496 |
| 17 | 51, 17, 77, 496 |
| 3, 1, 77, 496 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 3 x 1 x 77 x 496 = 42851424
Therefore, the lowest common multiple of 102,187,847,992 is 42851424.
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.
102 x 187 x 847 x 992 = 16026432576
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
187 : 1, 11, 17, 187
847 : 1, 7, 11, 77, 121, 847
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,187,847,992, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
187:11x 17
847:7x 11x 11
992:2x 2x 2x 2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 16026432576/(1x374)
LCM = 16026432576/374
LCM = 42851424
Thus, we can understand that the LCM of 102,187,847,992 is 42851424.
