The LCM of 551,159,493,646 is 2978706.
Find LCM of 551,159,493,646 with Prime Factorization
| 17 | 551, 159, 493, 646 |
| 19 | 551, 159, 29, 38 |
| 29 | 29, 159, 29, 2 |
| 1, 159, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 29 x 1 x 159 x 1 x 2 = 2978706
Therefore, the lowest common multiple of 551,159,493,646 is 2978706.
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 159 x 493 x 646 = 27901539102
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
159 : 1, 3, 53, 159
493 : 1, 17, 29, 493
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,159,493,646, is 1.
Now, the common factors can be found like this.
551:19x 29
159:3x 53
493:17x 29
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19x 29 = 9367
Therefore, the value for common factors is 9367.
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 = 27901539102/(1x9367)
LCM = 27901539102/9367
LCM = 2978706
Thus, we can understand that the LCM of 551,159,493,646 is 2978706.
