Given numbers are 453,973,721,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,973,721,961 is 43628637927.
Find LCM of 453,973,721,961 with Prime Factorization
| 7 | 453, 973, 721, 961 |
| 453, 139, 103, 961 |
Multiply the prime numbers at the bottom and the left side.
7 x 453 x 139 x 103 x 961 = 43628637927
Therefore, the lowest common multiple of 453,973,721,961 is 43628637927.
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.
453 x 973 x 721 x 961 = 305400465489
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.
453 : 1, 3, 151, 453
973 : 1, 7, 139, 973
721 : 1, 7, 103, 721
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,973,721,961, is 1.
Now, the common factors can be found like this.
453:3x 151
973:7x 139
721:7x 103
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 305400465489/(1x7)
LCM = 305400465489/7
LCM = 43628637927
Thus, we can understand that the LCM of 453,973,721,961 is 43628637927.
