Find LCM of 381,905,224,749,444 with Prime Factorization
| 2 | 381, 905, 224, 749, 444 |
| 2 | 381, 905, 112, 749, 222 |
| 3 | 381, 905, 56, 749, 111 |
| 7 | 127, 905, 56, 749, 37 |
| 127, 905, 8, 107, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 127 x 905 x 8 x 107 x 37 = 305778590880
Therefore, the lowest common multiple of 381,905,224,749,444 is 305778590880.
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.
381 x 905 x 224 x 749 x 444 = 25685401633920
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.
381 : 1, 3, 127, 381
905 : 1, 5, 181, 905
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
749 : 1, 7, 107, 749
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,905,224,749,444, is 1.
Now, the common factors can be found like this.
381:3x 127
905:5x 181
224:2x 2x 2x 2x 2x 7
749:7x 107
444:2x 2x 3x 37
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 25685401633920/(1x84)
LCM = 25685401633920/84
LCM = 305778590880
Thus, we can understand that the LCM of 381,905,224,749,444 is 305778590880.
