Given numbers are 655,684,346,685,677
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,684,346,685,677 is 7188739407540.
Find LCM of 655,684,346,685,677 with Prime Factorization
| 2 | 655, 684, 346, 685, 677 |
| 5 | 655, 342, 173, 685, 677 |
| 131, 342, 173, 137, 677 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 131 x 342 x 173 x 137 x 677 = 7188739407540
Therefore, the lowest common multiple of 655,684,346,685,677 is 7188739407540.
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.
655 x 684 x 346 x 685 x 677 = 71887394075400
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.
655 : 1, 5, 131, 655
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
346 : 1, 2, 173, 346
685 : 1, 5, 137, 685
677 : 1, 677
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,684,346,685,677, is 1.
Now, the common factors can be found like this.
655:5x 131
684:2x 2x 3x 3x 19
346:2x 173
685:5x 137
677:677
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 71887394075400/(1x10)
LCM = 71887394075400/10
LCM = 7188739407540
Thus, we can understand that the LCM of 655,684,346,685,677 is 7188739407540.
