Given numbers are 680,986,916,634,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,986,916,634,669 is 957696219240.
Find LCM of 680,986,916,634,669 with Prime Factorization
| 2 | 680, 986, 916, 634, 669 |
| 2 | 340, 493, 458, 317, 669 |
| 17 | 170, 493, 229, 317, 669 |
| 10, 29, 229, 317, 669 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 10 x 29 x 229 x 317 x 669 = 957696219240
Therefore, the lowest common multiple of 680,986,916,634,669 is 957696219240.
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.
680 x 986 x 916 x 634 x 669 = 260493371633280
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
986 : 1, 2, 17, 29, 34, 58, 493, 986
916 : 1, 2, 4, 229, 458, 916
634 : 1, 2, 317, 634
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,986,916,634,669, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
986:2x 17x 29
916:2x 2x 229
634:2x 317
669:3x 223
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 17 = 272
Therefore, the value for common factors is 272.
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 = 260493371633280/(1x272)
LCM = 260493371633280/272
LCM = 957696219240
Thus, we can understand that the LCM of 680,986,916,634,669 is 957696219240.
