The LCM of 749,642,124,782,276 is 108943548.
Find LCM of 749,642,124,782,276 with Prime Factorization
| 2 | 749, 642, 124, 782, 276 |
| 2 | 749, 321, 62, 391, 138 |
| 3 | 749, 321, 31, 391, 69 |
| 23 | 749, 107, 31, 391, 23 |
| 107 | 749, 107, 31, 17, 1 |
| 7, 1, 31, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 107 x 7 x 1 x 31 x 17 x 1 = 108943548
Therefore, the lowest common multiple of 749,642,124,782,276 is 108943548.
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 642 x 124 x 782 x 276 = 12869283438144
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
642 : 1, 2, 3, 6, 107, 214, 321, 642
124 : 1, 2, 4, 31, 62, 124
782 : 1, 2, 17, 23, 34, 46, 391, 782
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,642,124,782,276, is 1.
Now, the common factors can be found like this.
749:7x 107
642:2x 3x 107
124:2x 2x 31
782:2x 17x 23
276:2x 2x 3x 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 2x 2x 3x 23x 107 = 118128
Therefore, the value for common factors is 118128.
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 = 12869283438144/(1x118128)
LCM = 12869283438144/118128
LCM = 108943548
Thus, we can understand that the LCM of 749,642,124,782,276 is 108943548.
