Find LCM of 544,148,442,336,420 with Prime Factorization
| 2 | 544, 148, 442, 336, 420 |
| 2 | 272, 74, 221, 168, 210 |
| 2 | 136, 37, 221, 84, 105 |
| 2 | 68, 37, 221, 42, 105 |
| 3 | 34, 37, 221, 21, 105 |
| 7 | 34, 37, 221, 7, 35 |
| 17 | 34, 37, 221, 1, 5 |
| 2, 37, 13, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 7 x 17 x 2 x 37 x 13 x 1 x 5 = 27474720
Therefore, the lowest common multiple of 544,148,442,336,420 is 27474720.
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.
544 x 148 x 442 x 336 x 420 = 5021939220480
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.
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
148 : 1, 2, 4, 37, 74, 148
442 : 1, 2, 13, 17, 26, 34, 221, 442
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 544,148,442,336,420, is 2.
Now, the common factors can be found like this.
544:2x 2x 2x 2x 2x 17
148:2x 2x 37
442:2x 13x 17
336:2x 2x 2x 2x 3x 7
420:2x 2x 3x 5x 7
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 2x 2x 2x 2x 3x 7x 17 = 91392
Therefore, the value for common factors is 91392.
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 = 5021939220480/(2x91392)
LCM = 5021939220480/182784
LCM = 27474720
Thus, we can understand that the LCM of 544,148,442,336,420 is 27474720.
