Given numbers are 214,646,980,551,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 214,646,980,551,957 is 32413379460.
Find LCM of 214,646,980,551,957 with Prime Factorization
| 2 | 214, 646, 980, 551, 957 |
| 19 | 107, 323, 490, 551, 957 |
| 29 | 107, 17, 490, 29, 957 |
| 107, 17, 490, 1, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 29 x 107 x 17 x 490 x 1 x 33 = 32413379460
Therefore, the lowest common multiple of 214,646,980,551,957 is 32413379460.
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.
214 x 646 x 980 x 551 x 957 = 71439088329840
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.
214 : 1, 2, 107, 214
646 : 1, 2, 17, 19, 34, 38, 323, 646
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
551 : 1, 19, 29, 551
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 214,646,980,551,957, is 1.
Now, the common factors can be found like this.
214:2x 107
646:2x 17x 19
980:2x 2x 5x 7x 7
551:19x 29
957:3x 11x 29
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 19x 29 = 2204
Therefore, the value for common factors is 2204.
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 = 71439088329840/(1x2204)
LCM = 71439088329840/2204
LCM = 32413379460
Thus, we can understand that the LCM of 214,646,980,551,957 is 32413379460.
