Given numbers are 557,938,260,201,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,938,260,201,428 is 21802506180.
Find LCM of 557,938,260,201,428 with Prime Factorization
| 2 | 557, 938, 260, 201, 428 |
| 2 | 557, 469, 130, 201, 214 |
| 67 | 557, 469, 65, 201, 107 |
| 557, 7, 65, 3, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 67 x 557 x 7 x 65 x 3 x 107 = 21802506180
Therefore, the lowest common multiple of 557,938,260,201,428 is 21802506180.
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 938 x 260 x 201 x 428 = 11686143312480
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
938 : 1, 2, 7, 14, 67, 134, 469, 938
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
201 : 1, 3, 67, 201
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,938,260,201,428, is 1.
Now, the common factors can be found like this.
557:557
938:2x 7x 67
260:2x 2x 5x 13
201:3x 67
428:2x 2x 107
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 67 = 536
Therefore, the value for common factors is 536.
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 = 11686143312480/(1x536)
LCM = 11686143312480/536
LCM = 21802506180
Thus, we can understand that the LCM of 557,938,260,201,428 is 21802506180.
