Given numbers are 476,961,905,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,961,905,100 is 2069897900.
Find LCM of 476,961,905,100 with Prime Factorization
| 2 | 476, 961, 905, 100 |
| 2 | 238, 961, 905, 50 |
| 5 | 119, 961, 905, 25 |
| 119, 961, 181, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 119 x 961 x 181 x 5 = 2069897900
Therefore, the lowest common multiple of 476,961,905,100 is 2069897900.
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.
476 x 961 x 905 x 100 = 41397958000
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
961 : 1, 31, 961
905 : 1, 5, 181, 905
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,961,905,100, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
961:31x 31
905:5x 181
100:2x 2x 5x 5
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 5 = 20
Therefore, the value for common factors is 20.
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 = 41397958000/(1x20)
LCM = 41397958000/20
LCM = 2069897900
Thus, we can understand that the LCM of 476,961,905,100 is 2069897900.
