Find LCM of 749,589,308,484,391 with Prime Factorization
| 2 | 749, 589, 308, 484, 391 |
| 2 | 749, 589, 154, 242, 391 |
| 7 | 749, 589, 77, 121, 391 |
| 11 | 107, 589, 11, 121, 391 |
| 107, 589, 1, 11, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 107 x 589 x 1 x 11 x 391 = 83487072284
Therefore, the lowest common multiple of 749,589,308,484,391 is 83487072284.
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.
749 x 589 x 308 x 484 x 391 = 25714018263472
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.
749 : 1, 7, 107, 749
589 : 1, 19, 31, 589
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,589,308,484,391, is 1.
Now, the common factors can be found like this.
749:7x 107
589:19x 31
308:2x 2x 7x 11
484:2x 2x 11x 11
391:17x 23
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 25714018263472/(1x308)
LCM = 25714018263472/308
LCM = 83487072284
Thus, we can understand that the LCM of 749,589,308,484,391 is 83487072284.
