Given numbers are 307,930,658,342,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 307,930,658,342,987 is 5354169030.
Find LCM of 307,930,658,342,987 with Prime Factorization
| 2 | 307, 930, 658, 342, 987 |
| 3 | 307, 465, 329, 171, 987 |
| 7 | 307, 155, 329, 57, 329 |
| 47 | 307, 155, 47, 57, 47 |
| 307, 155, 1, 57, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 307 x 155 x 1 x 57 x 1 = 5354169030
Therefore, the lowest common multiple of 307,930,658,342,987 is 5354169030.
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.
307 x 930 x 658 x 342 x 987 = 63414777991320
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.
307 : 1, 307
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
658 : 1, 2, 7, 14, 47, 94, 329, 658
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,930,658,342,987, is 1.
Now, the common factors can be found like this.
307:307
930:2x 3x 5x 31
658:2x 7x 47
342:2x 3x 3x 19
987:3x 7x 47
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 7x 47 = 11844
Therefore, the value for common factors is 11844.
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 = 63414777991320/(1x11844)
LCM = 63414777991320/11844
LCM = 5354169030
Thus, we can understand that the LCM of 307,930,658,342,987 is 5354169030.
