Given numbers are 397,324,878,765,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,324,878,765,902 is 2164688972820.
Find LCM of 397,324,878,765,902 with Prime Factorization
| 2 | 397, 324, 878, 765, 902 |
| 3 | 397, 162, 439, 765, 451 |
| 3 | 397, 54, 439, 255, 451 |
| 397, 18, 439, 85, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 397 x 18 x 439 x 85 x 451 = 2164688972820
Therefore, the lowest common multiple of 397,324,878,765,902 is 2164688972820.
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.
397 x 324 x 878 x 765 x 902 = 77928803021520
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.
397 : 1, 397
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
878 : 1, 2, 439, 878
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,324,878,765,902, is 1.
Now, the common factors can be found like this.
397:397
324:2x 2x 3x 3x 3x 3
878:2x 439
765:3x 3x 5x 17
902:2x 11x 41
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 77928803021520/(1x36)
LCM = 77928803021520/36
LCM = 2164688972820
Thus, we can understand that the LCM of 397,324,878,765,902 is 2164688972820.
