Given numbers are 568,661,143,842,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 568,661,143,842,144 is 406855726992.
Find LCM of 568,661,143,842,144 with Prime Factorization
| 2 | 568, 661, 143, 842, 144 |
| 2 | 284, 661, 143, 421, 72 |
| 2 | 142, 661, 143, 421, 36 |
| 71, 661, 143, 421, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 71 x 661 x 143 x 421 x 18 = 406855726992
Therefore, the lowest common multiple of 568,661,143,842,144 is 406855726992.
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.
568 x 661 x 143 x 842 x 144 = 6509691631872
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.
568 : 1, 2, 4, 8, 71, 142, 284, 568
661 : 1, 661
143 : 1, 11, 13, 143
842 : 1, 2, 421, 842
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,661,143,842,144, is 1.
Now, the common factors can be found like this.
568:2x 2x 2x 71
661:661
143:11x 13
842:2x 421
144:2x 2x 2x 2x 3x 3
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 2 = 16
Therefore, the value for common factors is 16.
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 = 6509691631872/(1x16)
LCM = 6509691631872/16
LCM = 406855726992
Thus, we can understand that the LCM of 568,661,143,842,144 is 406855726992.
