Find LCM of 820,741,868,988,552 with Prime Factorization
| 2 | 820, 741, 868, 988, 552 |
| 2 | 410, 741, 434, 494, 276 |
| 3 | 205, 741, 217, 247, 138 |
| 13 | 205, 247, 217, 247, 46 |
| 19 | 205, 19, 217, 19, 46 |
| 205, 1, 217, 1, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 19 x 205 x 1 x 217 x 1 x 46 = 6065262840
Therefore, the lowest common multiple of 820,741,868,988,552 is 6065262840.
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.
820 x 741 x 868 x 988 x 552 = 287639024924160
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
741 : 1, 3, 13, 19, 39, 57, 247, 741
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,741,868,988,552, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
741:3x 13x 19
868:2x 2x 7x 31
988:2x 2x 13x 19
552:2x 2x 2x 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 2x 2x 2x 2x 3x 13x 19 = 47424
Therefore, the value for common factors is 47424.
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 = 287639024924160/(1x47424)
LCM = 287639024924160/47424
LCM = 6065262840
Thus, we can understand that the LCM of 820,741,868,988,552 is 6065262840.
