Find LCM of 501,749,788,749,642 with Prime Factorization
| 2 | 501, 749, 788, 749, 642 |
| 3 | 501, 749, 394, 749, 321 |
| 7 | 167, 749, 394, 749, 107 |
| 107 | 167, 107, 394, 107, 107 |
| 167, 1, 394, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 107 x 167 x 1 x 394 x 1 x 1 = 295696212
Therefore, the lowest common multiple of 501,749,788,749,642 is 295696212.
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.
501 x 749 x 788 x 749 x 642 = 142187889109896
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.
501 : 1, 3, 167, 501
749 : 1, 7, 107, 749
788 : 1, 2, 4, 197, 394, 788
749 : 1, 7, 107, 749
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,749,788,749,642, is 1.
Now, the common factors can be found like this.
501:3x 167
749:7x 107
788:2x 2x 197
749:7x 107
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 107x 107 = 480858
Therefore, the value for common factors is 480858.
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 = 142187889109896/(1x480858)
LCM = 142187889109896/480858
LCM = 295696212
Thus, we can understand that the LCM of 501,749,788,749,642 is 295696212.
