Given numbers are 657,174,783,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,174,783,648 is 1371816.
Find LCM of 657,174,783,648 with Prime Factorization
| 2 | 657, 174, 783, 648 |
| 3 | 657, 87, 783, 324 |
| 3 | 219, 29, 261, 108 |
| 3 | 73, 29, 87, 36 |
| 29 | 73, 29, 29, 12 |
| 73, 1, 1, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 29 x 73 x 1 x 1 x 12 = 1371816
Therefore, the lowest common multiple of 657,174,783,648 is 1371816.
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.
657 x 174 x 783 x 648 = 58003124112
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.
657 : 1, 3, 9, 73, 219, 657
174 : 1, 2, 3, 6, 29, 58, 87, 174
783 : 1, 3, 9, 27, 29, 87, 261, 783
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,174,783,648, is 3.
Now, the common factors can be found like this.
657:3x 3x 73
174:2x 3x 29
783:3x 3x 3x 29
648:2x 2x 2x 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 3x 3x 3x 3x 3x 29 = 14094
Therefore, the value for common factors is 14094.
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 = 58003124112/(3x14094)
LCM = 58003124112/42282
LCM = 1371816
Thus, we can understand that the LCM of 657,174,783,648 is 1371816.
