Given numbers are 390,989,897,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,989,897,767 is 22756890.
Find LCM of 390,989,897,767 with Prime Factorization
| 3 | 390, 989, 897, 767 |
| 13 | 130, 989, 299, 767 |
| 23 | 10, 989, 23, 59 |
| 10, 43, 1, 59 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 23 x 10 x 43 x 1 x 59 = 22756890
Therefore, the lowest common multiple of 390,989,897,767 is 22756890.
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.
390 x 989 x 897 x 767 = 265368094290
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
989 : 1, 23, 43, 989
897 : 1, 3, 13, 23, 39, 69, 299, 897
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,989,897,767, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
989:23x 43
897:3x 13x 23
767:13x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13x 23 = 11661
Therefore, the value for common factors is 11661.
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 = 265368094290/(1x11661)
LCM = 265368094290/11661
LCM = 22756890
Thus, we can understand that the LCM of 390,989,897,767 is 22756890.
