Given numbers are 557,155,551,990,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,155,551,990,898 is 4229120147670.
Find LCM of 557,155,551,990,898 with Prime Factorization
2 | 557, 155, 551, 990, 898 |
5 | 557, 155, 551, 495, 449 |
557, 31, 551, 99, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 557 x 31 x 551 x 99 x 449 = 4229120147670
Therefore, the lowest common multiple of 557,155,551,990,898 is 4229120147670.
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.
557 x 155 x 551 x 990 x 898 = 42291201476700
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.
557 : 1, 557
155 : 1, 5, 31, 155
551 : 1, 19, 29, 551
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,155,551,990,898, is 1.
Now, the common factors can be found like this.
557:557
155:5x 31
551:19x 29
990:2x 3x 3x 5x 11
898:2x 449
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 42291201476700/(1x10)
LCM = 42291201476700/10
LCM = 4229120147670
Thus, we can understand that the LCM of 557,155,551,990,898 is 4229120147670.
