Given numbers are 814,370,814,648,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,370,814,648,220 is 1318680.
Find LCM of 814,370,814,648,220 with Prime Factorization
| 2 | 814, 370, 814, 648, 220 |
| 2 | 407, 185, 407, 324, 110 |
| 5 | 407, 185, 407, 162, 55 |
| 11 | 407, 37, 407, 162, 11 |
| 37 | 37, 37, 37, 162, 1 |
| 1, 1, 1, 162, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 37 x 1 x 1 x 1 x 162 x 1 = 1318680
Therefore, the lowest common multiple of 814,370,814,648,220 is 1318680.
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.
814 x 370 x 814 x 648 x 220 = 34950083731200
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
370 : 1, 2, 5, 10, 37, 74, 185, 370
814 : 1, 2, 11, 22, 37, 74, 407, 814
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,370,814,648,220, is 2.
Now, the common factors can be found like this.
814:2x 11x 37
370:2x 5x 37
814:2x 11x 37
648:2x 2x 2x 3x 3x 3x 3
220:2x 2x 5x 11
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 5x 11x 11x 37x 37 = 13251920
Therefore, the value for common factors is 13251920.
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 = 34950083731200/(2x13251920)
LCM = 34950083731200/26503840
LCM = 1318680
Thus, we can understand that the LCM of 814,370,814,648,220 is 1318680.
