Given numbers are 103,515,390,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,515,390,676 is 1044420.
Find LCM of 103,515,390,676 with Prime Factorization
| 2 | 103, 515, 390, 676 |
| 5 | 103, 515, 195, 338 |
| 13 | 103, 103, 39, 338 |
| 103 | 103, 103, 3, 26 |
| 1, 1, 3, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 103 x 1 x 1 x 3 x 26 = 1044420
Therefore, the lowest common multiple of 103,515,390,676 is 1044420.
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.
103 x 515 x 390 x 676 = 13984783800
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.
103 : 1, 103
515 : 1, 5, 103, 515
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,515,390,676, is 1.
Now, the common factors can be found like this.
103:103
515:5x 103
390:2x 3x 5x 13
676:2x 2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 103 = 13390
Therefore, the value for common factors is 13390.
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 = 13984783800/(1x13390)
LCM = 13984783800/13390
LCM = 1044420
Thus, we can understand that the LCM of 103,515,390,676 is 1044420.
