Given numbers are 556,890,463,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,890,463,642 is 36772302660.
Find LCM of 556,890,463,642 with Prime Factorization
| 2 | 556, 890, 463, 642 |
| 278, 445, 463, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 278 x 445 x 463 x 321 = 36772302660
Therefore, the lowest common multiple of 556,890,463,642 is 36772302660.
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.
556 x 890 x 463 x 642 = 147089210640
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.
556 : 1, 2, 4, 139, 278, 556
890 : 1, 2, 5, 10, 89, 178, 445, 890
463 : 1, 463
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,890,463,642, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
890:2x 5x 89
463:463
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 147089210640/(1x4)
LCM = 147089210640/4
LCM = 36772302660
Thus, we can understand that the LCM of 556,890,463,642 is 36772302660.
