The LCM of 552,847,220,621 is 21039480.
Find LCM of 552,847,220,621 with Prime Factorization
| 2 | 552, 847, 220, 621 |
| 2 | 276, 847, 110, 621 |
| 3 | 138, 847, 55, 621 |
| 11 | 46, 847, 55, 207 |
| 23 | 46, 77, 5, 207 |
| 2, 77, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 23 x 2 x 77 x 5 x 9 = 21039480
Therefore, the lowest common multiple of 552,847,220,621 is 21039480.
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.
552 x 847 x 220 x 621 = 63875861280
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.
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
847 : 1, 7, 11, 77, 121, 847
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 552,847,220,621, is 1.
Now, the common factors can be found like this.
552:2x 2x 2x 3x 23
847:7x 11x 11
220:2x 2x 5x 11
621:3x 3x 3x 23
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 11x 23 = 3036
Therefore, the value for common factors is 3036.
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 = 63875861280/(1x3036)
LCM = 63875861280/3036
LCM = 21039480
Thus, we can understand that the LCM of 552,847,220,621 is 21039480.
