Find LCM of 642,955,825,889,254 with Prime Factorization
| 2 | 642, 955, 825, 889, 254 |
| 3 | 321, 955, 825, 889, 127 |
| 5 | 107, 955, 275, 889, 127 |
| 127 | 107, 191, 55, 889, 127 |
| 107, 191, 55, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 127 x 107 x 191 x 55 x 7 x 1 = 29978013450
Therefore, the lowest common multiple of 642,955,825,889,254 is 29978013450.
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 955 x 825 x 889 x 254 = 114216231244500
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
955 : 1, 5, 191, 955
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
889 : 1, 7, 127, 889
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,955,825,889,254, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
955:5x 191
825:3x 5x 5x 11
889:7x 127
254:2x 127
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 5x 127 = 3810
Therefore, the value for common factors is 3810.
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 = 114216231244500/(1x3810)
LCM = 114216231244500/3810
LCM = 29978013450
Thus, we can understand that the LCM of 642,955,825,889,254 is 29978013450.
