Find LCM of 878,990,697,990,557 with Prime Factorization
2 | 878, 990, 697, 990, 557 |
3 | 439, 495, 697, 495, 557 |
3 | 439, 165, 697, 165, 557 |
5 | 439, 55, 697, 55, 557 |
11 | 439, 11, 697, 11, 557 |
439, 1, 697, 1, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 439 x 1 x 697 x 1 x 557 = 168728205690
Therefore, the lowest common multiple of 878,990,697,990,557 is 168728205690.
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.
878 x 990 x 697 x 990 x 557 = 334081847266200
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.
878 : 1, 2, 439, 878
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
697 : 1, 17, 41, 697
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
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,990,697,990,557, is 1.
Now, the common factors can be found like this.
878:2x 439
990:2x 3x 3x 5x 11
697:17x 41
990:2x 3x 3x 5x 11
557:557
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 3x 3x 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 334081847266200/(1x1980)
LCM = 334081847266200/1980
LCM = 168728205690
Thus, we can understand that the LCM of 878,990,697,990,557 is 168728205690.
