Find LCM of 471,870,749,642,705 with Prime Factorization
| 2 | 471, 870, 749, 642, 705 |
| 3 | 471, 435, 749, 321, 705 |
| 5 | 157, 145, 749, 107, 235 |
| 107 | 157, 29, 749, 107, 47 |
| 157, 29, 7, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 157 x 29 x 7 x 1 x 47 = 4808377770
Therefore, the lowest common multiple of 471,870,749,642,705 is 4808377770.
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.
471 x 870 x 749 x 642 x 705 = 138914033775300
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.
471 : 1, 3, 157, 471
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
749 : 1, 7, 107, 749
642 : 1, 2, 3, 6, 107, 214, 321, 642
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,870,749,642,705, is 1.
Now, the common factors can be found like this.
471:3x 157
870:2x 3x 5x 29
749:7x 107
642:2x 3x 107
705:3x 5x 47
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 3x 3x 5x 107 = 28890
Therefore, the value for common factors is 28890.
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 = 138914033775300/(1x28890)
LCM = 138914033775300/28890
LCM = 4808377770
Thus, we can understand that the LCM of 471,870,749,642,705 is 4808377770.
