Find LCM of 556,554,209,209,787 with Prime Factorization
| 2 | 556, 554, 209, 209, 787 |
| 11 | 278, 277, 209, 209, 787 |
| 19 | 278, 277, 19, 19, 787 |
| 278, 277, 1, 1, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 278 x 277 x 1 x 1 x 787 = 25332355796
Therefore, the lowest common multiple of 556,554,209,209,787 is 25332355796.
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 554 x 209 x 209 x 787 = 10588924722728
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
554 : 1, 2, 277, 554
209 : 1, 11, 19, 209
209 : 1, 11, 19, 209
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,554,209,209,787, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
554:2x 277
209:11x 19
209:11x 19
787:787
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 19 = 418
Therefore, the value for common factors is 418.
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 = 10588924722728/(1x418)
LCM = 10588924722728/418
LCM = 25332355796
Thus, we can understand that the LCM of 556,554,209,209,787 is 25332355796.
