Given numbers are 930,786,988,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 930,786,988,361 is 1143496380.
Find LCM of 930,786,988,361 with Prime Factorization
| 2 | 930, 786, 988, 361 |
| 3 | 465, 393, 494, 361 |
| 19 | 155, 131, 494, 361 |
| 155, 131, 26, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 155 x 131 x 26 x 19 = 1143496380
Therefore, the lowest common multiple of 930,786,988,361 is 1143496380.
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.
930 x 786 x 988 x 361 = 260717174640
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
786 : 1, 2, 3, 6, 131, 262, 393, 786
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,786,988,361, is 1.
Now, the common factors can be found like this.
930:2x 3x 5x 31
786:2x 3x 131
988:2x 2x 13x 19
361:19x 19
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 19 = 228
Therefore, the value for common factors is 228.
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 = 260717174640/(1x228)
LCM = 260717174640/228
LCM = 1143496380
Thus, we can understand that the LCM of 930,786,988,361 is 1143496380.
