The LCM of 551,458,520,620,858 is 67122180840.
Find LCM of 551,458,520,620,858 with Prime Factorization
| 2 | 551, 458, 520, 620, 858 |
| 2 | 551, 229, 260, 310, 429 |
| 5 | 551, 229, 130, 155, 429 |
| 13 | 551, 229, 26, 31, 429 |
| 551, 229, 2, 31, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 551 x 229 x 2 x 31 x 33 = 67122180840
Therefore, the lowest common multiple of 551,458,520,620,858 is 67122180840.
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.
551 x 458 x 520 x 620 x 858 = 69807068073600
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.
551 : 1, 19, 29, 551
458 : 1, 2, 229, 458
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,458,520,620,858, is 1.
Now, the common factors can be found like this.
551:19x 29
458:2x 229
520:2x 2x 2x 5x 13
620:2x 2x 5x 31
858:2x 3x 11x 13
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 5x 13 = 1040
Therefore, the value for common factors is 1040.
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 = 69807068073600/(1x1040)
LCM = 69807068073600/1040
LCM = 67122180840
Thus, we can understand that the LCM of 551,458,520,620,858 is 67122180840.
