Given numbers are 434,103,309,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 434,103,309,556 is 37281468.
Find LCM of 434,103,309,556 with Prime Factorization
| 2 | 434, 103, 309, 556 |
| 103 | 217, 103, 309, 278 |
| 217, 1, 3, 278 |
Multiply the prime numbers at the bottom and the left side.
2 x 103 x 217 x 1 x 3 x 278 = 37281468
Therefore, the lowest common multiple of 434,103,309,556 is 37281468.
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.
434 x 103 x 309 x 556 = 7679982408
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.
434 : 1, 2, 7, 14, 31, 62, 217, 434
103 : 1, 103
309 : 1, 3, 103, 309
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,103,309,556, is 1.
Now, the common factors can be found like this.
434:2x 7x 31
103:103
309:3x 103
556:2x 2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 103 = 206
Therefore, the value for common factors is 206.
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 = 7679982408/(1x206)
LCM = 7679982408/206
LCM = 37281468
Thus, we can understand that the LCM of 434,103,309,556 is 37281468.
