Given numbers are 470,940,989,923,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,940,989,923,346 is 148447179140.
Find LCM of 470,940,989,923,346 with Prime Factorization
| 2 | 470, 940, 989, 923, 346 |
| 5 | 235, 470, 989, 923, 173 |
| 47 | 47, 94, 989, 923, 173 |
| 1, 2, 989, 923, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 47 x 1 x 2 x 989 x 923 x 173 = 148447179140
Therefore, the lowest common multiple of 470,940,989,923,346 is 148447179140.
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.
470 x 940 x 989 x 923 x 346 = 139540348391600
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
989 : 1, 23, 43, 989
923 : 1, 13, 71, 923
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,940,989,923,346, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
940:2x 2x 5x 47
989:23x 43
923:13x 71
346:2x 173
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 5x 47 = 940
Therefore, the value for common factors is 940.
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 = 139540348391600/(1x940)
LCM = 139540348391600/940
LCM = 148447179140
Thus, we can understand that the LCM of 470,940,989,923,346 is 148447179140.
