Find LCM of 837,561,540,391,553 with Prime Factorization
| 3 | 837, 561, 540, 391, 553 |
| 3 | 279, 187, 180, 391, 553 |
| 3 | 93, 187, 60, 391, 553 |
| 17 | 31, 187, 20, 391, 553 |
| 31, 11, 20, 23, 553 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 17 x 31 x 11 x 20 x 23 x 553 = 39815303220
Therefore, the lowest common multiple of 837,561,540,391,553 is 39815303220.
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.
837 x 561 x 540 x 391 x 553 = 54825672533940
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
561 : 1, 3, 11, 17, 33, 51, 187, 561
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
391 : 1, 17, 23, 391
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,561,540,391,553, is 1.
Now, the common factors can be found like this.
837:3x 3x 3x 31
561:3x 11x 17
540:2x 2x 3x 3x 3x 5
391:17x 23
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 17 = 1377
Therefore, the value for common factors is 1377.
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 = 54825672533940/(1x1377)
LCM = 54825672533940/1377
LCM = 39815303220
Thus, we can understand that the LCM of 837,561,540,391,553 is 39815303220.
