Find LCM of 551,490,833,782 with Prime Factorization
| 2 | 551, 490, 833, 782 |
| 7 | 551, 245, 833, 391 |
| 7 | 551, 35, 119, 391 |
| 17 | 551, 5, 17, 391 |
| 551, 5, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 17 x 551 x 5 x 1 x 23 = 105566090
Therefore, the lowest common multiple of 551,490,833,782 is 105566090.
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 490 x 833 x 782 = 175873105940
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
833 : 1, 7, 17, 49, 119, 833
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,490,833,782, is 1.
Now, the common factors can be found like this.
551:19x 29
490:2x 5x 7x 7
833:7x 7x 17
782:2x 17x 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 7x 7x 17 = 1666
Therefore, the value for common factors is 1666.
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 = 175873105940/(1x1666)
LCM = 175873105940/1666
LCM = 105566090
Thus, we can understand that the LCM of 551,490,833,782 is 105566090.
