Given numbers are 380,984,930,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,984,930,908 is 657818760.
Find LCM of 380,984,930,908 with Prime Factorization
| 2 | 380, 984, 930, 908 |
| 2 | 190, 492, 465, 454 |
| 3 | 95, 246, 465, 227 |
| 5 | 95, 82, 155, 227 |
| 19, 82, 31, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 82 x 31 x 227 = 657818760
Therefore, the lowest common multiple of 380,984,930,908 is 657818760.
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.
380 x 984 x 930 x 908 = 315753004800
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
908 : 1, 2, 4, 227, 454, 908
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,984,930,908, is 2.
Now, the common factors can be found like this.
380:2x 2x 5x 19
984:2x 2x 2x 3x 41
930:2x 3x 5x 31
908:2x 2x 227
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 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 315753004800/(2x240)
LCM = 315753004800/480
LCM = 657818760
Thus, we can understand that the LCM of 380,984,930,908 is 657818760.
