Find LCM of 642,210,707,477,825 with Prime Factorization
| 2 | 642, 210, 707, 477, 825 |
| 3 | 321, 105, 707, 477, 825 |
| 5 | 107, 35, 707, 159, 275 |
| 7 | 107, 7, 707, 159, 55 |
| 107, 1, 101, 159, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 107 x 1 x 101 x 159 x 55 = 19846515150
Therefore, the lowest common multiple of 642,210,707,477,825 is 19846515150.
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.
642 x 210 x 707 x 477 x 825 = 37509913633500
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
707 : 1, 7, 101, 707
477 : 1, 3, 9, 53, 159, 477
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,210,707,477,825, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
210:2x 3x 5x 7
707:7x 101
477:3x 3x 53
825:3x 5x 5x 11
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 7 = 1890
Therefore, the value for common factors is 1890.
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 = 37509913633500/(1x1890)
LCM = 37509913633500/1890
LCM = 19846515150
Thus, we can understand that the LCM of 642,210,707,477,825 is 19846515150.
