Given numbers are 897,765,842,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,765,842,612 is 385189740.
Find LCM of 897,765,842,612 with Prime Factorization
| 2 | 897, 765, 842, 612 |
| 3 | 897, 765, 421, 306 |
| 3 | 299, 255, 421, 102 |
| 17 | 299, 85, 421, 34 |
| 299, 5, 421, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 299 x 5 x 421 x 2 = 385189740
Therefore, the lowest common multiple of 897,765,842,612 is 385189740.
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.
897 x 765 x 842 x 612 = 353604181320
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
842 : 1, 2, 421, 842
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,765,842,612, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
765:3x 3x 5x 17
842:2x 421
612:2x 2x 3x 3x 17
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 3x 3x 17 = 918
Therefore, the value for common factors is 918.
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 = 353604181320/(1x918)
LCM = 353604181320/918
LCM = 385189740
Thus, we can understand that the LCM of 897,765,842,612 is 385189740.
