Given numbers are 558,338,908,620,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,338,908,620,721 is 154341254340.
Find LCM of 558,338,908,620,721 with Prime Factorization
| 2 | 558, 338, 908, 620, 721 |
| 2 | 279, 169, 454, 310, 721 |
| 31 | 279, 169, 227, 155, 721 |
| 9, 169, 227, 5, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 9 x 169 x 227 x 5 x 721 = 154341254340
Therefore, the lowest common multiple of 558,338,908,620,721 is 154341254340.
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.
558 x 338 x 908 x 620 x 721 = 76553262152640
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
338 : 1, 2, 13, 26, 169, 338
908 : 1, 2, 4, 227, 454, 908
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,338,908,620,721, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
338:2x 13x 13
908:2x 2x 227
620:2x 2x 5x 31
721:7x 103
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 2x 31 = 496
Therefore, the value for common factors is 496.
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 = 76553262152640/(1x496)
LCM = 76553262152640/496
LCM = 154341254340
Thus, we can understand that the LCM of 558,338,908,620,721 is 154341254340.
