Given numbers are 902,642,793,868
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,642,793,868 is 99649353804.
Find LCM of 902,642,793,868 with Prime Factorization
| 2 | 902, 642, 793, 868 |
| 451, 321, 793, 434 |
Multiply the prime numbers at the bottom and the left side.
2 x 451 x 321 x 793 x 434 = 99649353804
Therefore, the lowest common multiple of 902,642,793,868 is 99649353804.
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.
902 x 642 x 793 x 868 = 398597415216
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
642 : 1, 2, 3, 6, 107, 214, 321, 642
793 : 1, 13, 61, 793
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,642,793,868, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
642:2x 3x 107
793:13x 61
868:2x 2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 398597415216/(1x4)
LCM = 398597415216/4
LCM = 99649353804
Thus, we can understand that the LCM of 902,642,793,868 is 99649353804.
