Find LCM of 765,698,973,455,897 with Prime Factorization
| 3 | 765, 698, 973, 455, 897 |
| 5 | 255, 698, 973, 455, 299 |
| 7 | 51, 698, 973, 91, 299 |
| 13 | 51, 698, 139, 13, 299 |
| 51, 698, 139, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 13 x 51 x 698 x 139 x 1 x 23 = 155346290190
Therefore, the lowest common multiple of 765,698,973,455,897 is 155346290190.
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.
765 x 698 x 973 x 455 x 897 = 212047686109350
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
698 : 1, 2, 349, 698
973 : 1, 7, 139, 973
455 : 1, 5, 7, 13, 35, 65, 91, 455
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,698,973,455,897, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
698:2x 349
973:7x 139
455:5x 7x 13
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 13 = 1365
Therefore, the value for common factors is 1365.
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 = 212047686109350/(1x1365)
LCM = 212047686109350/1365
LCM = 155346290190
Thus, we can understand that the LCM of 765,698,973,455,897 is 155346290190.
