Given numbers are 721,275,418,166
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,275,418,166 is 625359350.
Find LCM of 721,275,418,166 with Prime Factorization
| 2 | 721, 275, 418, 166 |
| 11 | 721, 275, 209, 83 |
| 721, 25, 19, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 721 x 25 x 19 x 83 = 625359350
Therefore, the lowest common multiple of 721,275,418,166 is 625359350.
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.
721 x 275 x 418 x 166 = 13757905700
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.
721 : 1, 7, 103, 721
275 : 1, 5, 11, 25, 55, 275
418 : 1, 2, 11, 19, 22, 38, 209, 418
166 : 1, 2, 83, 166
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,275,418,166, is 1.
Now, the common factors can be found like this.
721:7x 103
275:5x 5x 11
418:2x 11x 19
166:2x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 13757905700/(1x22)
LCM = 13757905700/22
LCM = 625359350
Thus, we can understand that the LCM of 721,275,418,166 is 625359350.
