Given numbers are 684,662,354,240,281
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,662,354,240,281 is 75071038320.
Find LCM of 684,662,354,240,281 with Prime Factorization
| 2 | 684, 662, 354, 240, 281 |
| 2 | 342, 331, 177, 120, 281 |
| 3 | 171, 331, 177, 60, 281 |
| 57, 331, 59, 20, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 57 x 331 x 59 x 20 x 281 = 75071038320
Therefore, the lowest common multiple of 684,662,354,240,281 is 75071038320.
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.
684 x 662 x 354 x 240 x 281 = 10810229518080
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
662 : 1, 2, 331, 662
354 : 1, 2, 3, 6, 59, 118, 177, 354
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
281 : 1, 281
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,662,354,240,281, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
662:2x 331
354:2x 3x 59
240:2x 2x 2x 2x 3x 5
281:281
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 10810229518080/(1x144)
LCM = 10810229518080/144
LCM = 75071038320
Thus, we can understand that the LCM of 684,662,354,240,281 is 75071038320.
