Given numbers are 577,721,680,685,662
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 577,721,680,685,662 is 12828283571320.
Find LCM of 577,721,680,685,662 with Prime Factorization
| 2 | 577, 721, 680, 685, 662 |
| 5 | 577, 721, 340, 685, 331 |
| 577, 721, 68, 137, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 577 x 721 x 68 x 137 x 331 = 12828283571320
Therefore, the lowest common multiple of 577,721,680,685,662 is 12828283571320.
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.
577 x 721 x 680 x 685 x 662 = 128282835713200
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.
577 : 1, 577
721 : 1, 7, 103, 721
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
685 : 1, 5, 137, 685
662 : 1, 2, 331, 662
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,721,680,685,662, is 1.
Now, the common factors can be found like this.
577:577
721:7x 103
680:2x 2x 2x 5x 17
685:5x 137
662:2x 331
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 = 128282835713200/(1x10)
LCM = 128282835713200/10
LCM = 12828283571320
Thus, we can understand that the LCM of 577,721,680,685,662 is 12828283571320.
