Given numbers are 470,860,311,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,860,311,972 is 3054660660.
Find LCM of 470,860,311,972 with Prime Factorization
| 2 | 470, 860, 311, 972 |
| 2 | 235, 430, 311, 486 |
| 5 | 235, 215, 311, 243 |
| 47, 43, 311, 243 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 47 x 43 x 311 x 243 = 3054660660
Therefore, the lowest common multiple of 470,860,311,972 is 3054660660.
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 860 x 311 x 972 = 122186426400
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
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
311 : 1, 311
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,860,311,972, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
860:2x 2x 5x 43
311:311
972:2x 2x 3x 3x 3x 3x 3
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 122186426400/(1x40)
LCM = 122186426400/40
LCM = 3054660660
Thus, we can understand that the LCM of 470,860,311,972 is 3054660660.
