Given numbers are 551,686,574,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,686,574,738 is 139476834.
Find LCM of 551,686,574,738 with Prime Factorization
| 2 | 551, 686, 574, 738 |
| 7 | 551, 343, 287, 369 |
| 41 | 551, 49, 41, 369 |
| 551, 49, 1, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 551 x 49 x 1 x 9 = 139476834
Therefore, the lowest common multiple of 551,686,574,738 is 139476834.
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 686 x 574 x 738 = 160119405432
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
686 : 1, 2, 7, 14, 49, 98, 343, 686
574 : 1, 2, 7, 14, 41, 82, 287, 574
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,686,574,738, is 1.
Now, the common factors can be found like this.
551:19x 29
686:2x 7x 7x 7
574:2x 7x 41
738:2x 3x 3x 41
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 7x 41 = 1148
Therefore, the value for common factors is 1148.
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 = 160119405432/(1x1148)
LCM = 160119405432/1148
LCM = 139476834
Thus, we can understand that the LCM of 551,686,574,738 is 139476834.
