Given numbers are 345,930,918,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,930,918,680 is 13090680.
Find LCM of 345,930,918,680 with Prime Factorization
| 2 | 345, 930, 918, 680 |
| 3 | 345, 465, 459, 340 |
| 5 | 115, 155, 153, 340 |
| 17 | 23, 31, 153, 68 |
| 23, 31, 9, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 23 x 31 x 9 x 4 = 13090680
Therefore, the lowest common multiple of 345,930,918,680 is 13090680.
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.
345 x 930 x 918 x 680 = 200287404000
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,930,918,680, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
930:2x 3x 5x 31
918:2x 3x 3x 3x 17
680:2x 2x 2x 5x 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 2x 3x 3x 5x 5x 17 = 15300
Therefore, the value for common factors is 15300.
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 = 200287404000/(1x15300)
LCM = 200287404000/15300
LCM = 13090680
Thus, we can understand that the LCM of 345,930,918,680 is 13090680.
