Given numbers are 617,551,285,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 617,551,285,666 is 1132090110.
Find LCM of 617,551,285,666 with Prime Factorization
| 3 | 617, 551, 285, 666 |
| 19 | 617, 551, 95, 222 |
| 617, 29, 5, 222 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 617 x 29 x 5 x 222 = 1132090110
Therefore, the lowest common multiple of 617,551,285,666 is 1132090110.
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.
617 x 551 x 285 x 666 = 64529136270
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.
617 : 1, 617
551 : 1, 19, 29, 551
285 : 1, 3, 5, 15, 19, 57, 95, 285
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,551,285,666, is 1.
Now, the common factors can be found like this.
617:617
551:19x 29
285:3x 5x 19
666:2x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 64529136270/(1x57)
LCM = 64529136270/57
LCM = 1132090110
Thus, we can understand that the LCM of 617,551,285,666 is 1132090110.
