Given numbers are 291,991,875,798,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,991,875,798,845 is 1620484934250.
Find LCM of 291,991,875,798,845 with Prime Factorization
| 3 | 291, 991, 875, 798, 845 |
| 5 | 97, 991, 875, 266, 845 |
| 7 | 97, 991, 175, 266, 169 |
| 97, 991, 25, 38, 169 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 97 x 991 x 25 x 38 x 169 = 1620484934250
Therefore, the lowest common multiple of 291,991,875,798,845 is 1620484934250.
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.
291 x 991 x 875 x 798 x 845 = 170150918096250
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.
291 : 1, 3, 97, 291
991 : 1, 991
875 : 1, 5, 7, 25, 35, 125, 175, 875
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,991,875,798,845, is 1.
Now, the common factors can be found like this.
291:3x 97
991:991
875:5x 5x 5x 7
798:2x 3x 7x 19
845:5x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 170150918096250/(1x105)
LCM = 170150918096250/105
LCM = 1620484934250
Thus, we can understand that the LCM of 291,991,875,798,845 is 1620484934250.
