Given numbers are 556,559,138,253,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,559,138,253,154 is 1651301652.
Find LCM of 556,559,138,253,154 with Prime Factorization
| 2 | 556, 559, 138, 253, 154 |
| 11 | 278, 559, 69, 253, 77 |
| 23 | 278, 559, 69, 23, 7 |
| 278, 559, 3, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 278 x 559 x 3 x 1 x 7 = 1651301652
Therefore, the lowest common multiple of 556,559,138,253,154 is 1651301652.
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.
556 x 559 x 138 x 253 x 154 = 1671117271824
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.
556 : 1, 2, 4, 139, 278, 556
559 : 1, 13, 43, 559
138 : 1, 2, 3, 6, 23, 46, 69, 138
253 : 1, 11, 23, 253
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,559,138,253,154, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
559:13x 43
138:2x 3x 23
253:11x 23
154:2x 7x 11
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 11x 23 = 1012
Therefore, the value for common factors is 1012.
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 = 1671117271824/(1x1012)
LCM = 1671117271824/1012
LCM = 1651301652
Thus, we can understand that the LCM of 556,559,138,253,154 is 1651301652.
