Given numbers are 345,219,943,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,219,943,847 is 874599495.
Find LCM of 345,219,943,847 with Prime Factorization
| 3 | 345, 219, 943, 847 |
| 23 | 115, 73, 943, 847 |
| 5, 73, 41, 847 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 5 x 73 x 41 x 847 = 874599495
Therefore, the lowest common multiple of 345,219,943,847 is 874599495.
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.
345 x 219 x 943 x 847 = 60347365155
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
219 : 1, 3, 73, 219
943 : 1, 23, 41, 943
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,219,943,847, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
219:3x 73
943:23x 41
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23 = 69
Therefore, the value for common factors is 69.
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 = 60347365155/(1x69)
LCM = 60347365155/69
LCM = 874599495
Thus, we can understand that the LCM of 345,219,943,847 is 874599495.
