The LCM of 660,407,283,795,661 is 242108158380.
Find LCM of 660,407,283,795,661 with Prime Factorization
| 3 | 660, 407, 283, 795, 661 |
| 5 | 220, 407, 283, 265, 661 |
| 11 | 44, 407, 283, 53, 661 |
| 4, 37, 283, 53, 661 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 4 x 37 x 283 x 53 x 661 = 242108158380
Therefore, the lowest common multiple of 660,407,283,795,661 is 242108158380.
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.
660 x 407 x 283 x 795 x 661 = 39947846132700
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
407 : 1, 11, 37, 407
283 : 1, 283
795 : 1, 3, 5, 15, 53, 159, 265, 795
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,407,283,795,661, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
407:11x 37
283:283
795:3x 5x 53
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 39947846132700/(1x165)
LCM = 39947846132700/165
LCM = 242108158380
Thus, we can understand that the LCM of 660,407,283,795,661 is 242108158380.
