Given numbers are 646,147,964,192,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,147,964,192,109 is 79825816896.
Find LCM of 646,147,964,192,109 with Prime Factorization
| 2 | 646, 147, 964, 192, 109 |
| 2 | 323, 147, 482, 96, 109 |
| 3 | 323, 147, 241, 48, 109 |
| 323, 49, 241, 16, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 323 x 49 x 241 x 16 x 109 = 79825816896
Therefore, the lowest common multiple of 646,147,964,192,109 is 79825816896.
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.
646 x 147 x 964 x 192 x 109 = 1915819605504
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
147 : 1, 3, 7, 21, 49, 147
964 : 1, 2, 4, 241, 482, 964
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,147,964,192,109, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
147:3x 7x 7
964:2x 2x 241
192:2x 2x 2x 2x 2x 2x 3
109:109
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 3 = 24
Therefore, the value for common factors is 24.
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 = 1915819605504/(1x24)
LCM = 1915819605504/24
LCM = 79825816896
Thus, we can understand that the LCM of 646,147,964,192,109 is 79825816896.
