Given numbers are 969,497,518,338,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,497,518,338,821 is 4944720489618.
Find LCM of 969,497,518,338,821 with Prime Factorization
| 2 | 969, 497, 518, 338, 821 |
| 7 | 969, 497, 259, 169, 821 |
| 969, 71, 37, 169, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 969 x 71 x 37 x 169 x 821 = 4944720489618
Therefore, the lowest common multiple of 969,497,518,338,821 is 4944720489618.
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.
969 x 497 x 518 x 338 x 821 = 69226086854652
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
497 : 1, 7, 71, 497
518 : 1, 2, 7, 14, 37, 74, 259, 518
338 : 1, 2, 13, 26, 169, 338
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,497,518,338,821, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
497:7x 71
518:2x 7x 37
338:2x 13x 13
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 69226086854652/(1x14)
LCM = 69226086854652/14
LCM = 4944720489618
Thus, we can understand that the LCM of 969,497,518,338,821 is 4944720489618.
