Find LCM of 648,419,456,370,215 with Prime Factorization
| 2 | 648, 419, 456, 370, 215 |
| 2 | 324, 419, 228, 185, 215 |
| 2 | 162, 419, 114, 185, 215 |
| 3 | 81, 419, 57, 185, 215 |
| 5 | 27, 419, 19, 185, 215 |
| 27, 419, 19, 37, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 27 x 419 x 19 x 37 x 43 = 41037681240
Therefore, the lowest common multiple of 648,419,456,370,215 is 41037681240.
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.
648 x 419 x 456 x 370 x 215 = 9849043497600
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
419 : 1, 419
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
370 : 1, 2, 5, 10, 37, 74, 185, 370
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,419,456,370,215, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
419:419
456:2x 2x 2x 3x 19
370:2x 5x 37
215:5x 43
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 9849043497600/(1x240)
LCM = 9849043497600/240
LCM = 41037681240
Thus, we can understand that the LCM of 648,419,456,370,215 is 41037681240.
