Given numbers are 677,824,680,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,824,680,980 is 2323436920.
Find LCM of 677,824,680,980 with Prime Factorization
| 2 | 677, 824, 680, 980 |
| 2 | 677, 412, 340, 490 |
| 2 | 677, 206, 170, 245 |
| 5 | 677, 103, 85, 245 |
| 677, 103, 17, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 677 x 103 x 17 x 49 = 2323436920
Therefore, the lowest common multiple of 677,824,680,980 is 2323436920.
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.
677 x 824 x 680 x 980 = 371749907200
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.
677 : 1, 677
824 : 1, 2, 4, 8, 103, 206, 412, 824
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,824,680,980, is 1.
Now, the common factors can be found like this.
677:677
824:2x 2x 2x 103
680:2x 2x 2x 5x 17
980:2x 2x 5x 7x 7
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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 371749907200/(1x160)
LCM = 371749907200/160
LCM = 2323436920
Thus, we can understand that the LCM of 677,824,680,980 is 2323436920.
