Given numbers are 665,905,880,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,905,880,462 is 63552720.
Find LCM of 665,905,880,462 with Prime Factorization
| 2 | 665, 905, 880, 462 |
| 5 | 665, 905, 440, 231 |
| 7 | 133, 181, 88, 231 |
| 11 | 19, 181, 88, 33 |
| 19, 181, 8, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 19 x 181 x 8 x 3 = 63552720
Therefore, the lowest common multiple of 665,905,880,462 is 63552720.
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.
665 x 905 x 880 x 462 = 244677972000
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
905 : 1, 5, 181, 905
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,905,880,462, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
905:5x 181
880:2x 2x 2x 2x 5x 11
462:2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7x 11 = 3850
Therefore, the value for common factors is 3850.
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 = 244677972000/(1x3850)
LCM = 244677972000/3850
LCM = 63552720
Thus, we can understand that the LCM of 665,905,880,462 is 63552720.
