Given numbers are 444,892,100,647
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 444,892,100,647 is 1601519100.
Find LCM of 444,892,100,647 with Prime Factorization
| 2 | 444, 892, 100, 647 |
| 2 | 222, 446, 50, 647 |
| 111, 223, 25, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 111 x 223 x 25 x 647 = 1601519100
Therefore, the lowest common multiple of 444,892,100,647 is 1601519100.
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.
444 x 892 x 100 x 647 = 25624305600
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.
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
892 : 1, 2, 4, 223, 446, 892
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 444,892,100,647, is 1.
Now, the common factors can be found like this.
444:2x 2x 3x 37
892:2x 2x 223
100:2x 2x 5x 5
647:647
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 = 25624305600/(1x16)
LCM = 25624305600/16
LCM = 1601519100
Thus, we can understand that the LCM of 444,892,100,647 is 1601519100.
