Given numbers are 657,949,663,147,219
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,949,663,147,219 is 7114653.
Find LCM of 657,949,663,147,219 with Prime Factorization
| 3 | 657, 949, 663, 147, 219 |
| 13 | 219, 949, 221, 49, 73 |
| 73 | 219, 73, 17, 49, 73 |
| 3, 1, 17, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 73 x 3 x 1 x 17 x 49 x 1 = 7114653
Therefore, the lowest common multiple of 657,949,663,147,219 is 7114653.
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 949 x 663 x 147 x 219 = 13307809028787
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
949 : 1, 13, 73, 949
663 : 1, 3, 13, 17, 39, 51, 221, 663
147 : 1, 3, 7, 21, 49, 147
219 : 1, 3, 73, 219
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,949,663,147,219, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
949:13x 73
663:3x 13x 17
147:3x 7x 7
219:3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 13x 73x 73 = 1870479
Therefore, the value for common factors is 1870479.
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 = 13307809028787/(1x1870479)
LCM = 13307809028787/1870479
LCM = 7114653
Thus, we can understand that the LCM of 657,949,663,147,219 is 7114653.
