Given numbers are 107,646,988,272
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,646,988,272 is 7188688.
Find LCM of 107,646,988,272 with Prime Factorization
| 2 | 107, 646, 988, 272 |
| 2 | 107, 323, 494, 136 |
| 17 | 107, 323, 247, 68 |
| 19 | 107, 19, 247, 4 |
| 107, 1, 13, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 107 x 1 x 13 x 4 = 7188688
Therefore, the lowest common multiple of 107,646,988,272 is 7188688.
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.
107 x 646 x 988 x 272 = 18575569792
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.
107 : 1, 107
646 : 1, 2, 17, 19, 34, 38, 323, 646
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,646,988,272, is 1.
Now, the common factors can be found like this.
107:107
646:2x 17x 19
988:2x 2x 13x 19
272:2x 2x 2x 2x 17
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 17x 19 = 2584
Therefore, the value for common factors is 2584.
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 = 18575569792/(1x2584)
LCM = 18575569792/2584
LCM = 7188688
Thus, we can understand that the LCM of 107,646,988,272 is 7188688.
