Given numbers are 556,452,669,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,452,669,669 is 42031932.
Find LCM of 556,452,669,669 with Prime Factorization
| 2 | 556, 452, 669, 669 |
| 2 | 278, 226, 669, 669 |
| 3 | 139, 113, 669, 669 |
| 223 | 139, 113, 223, 223 |
| 139, 113, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 223 x 139 x 113 x 1 x 1 = 42031932
Therefore, the lowest common multiple of 556,452,669,669 is 42031932.
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.
556 x 452 x 669 x 669 = 112477450032
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.
556 : 1, 2, 4, 139, 278, 556
452 : 1, 2, 4, 113, 226, 452
669 : 1, 3, 223, 669
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,452,669,669, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
452:2x 2x 113
669:3x 223
669:3x 223
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 223 = 2676
Therefore, the value for common factors is 2676.
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 = 112477450032/(1x2676)
LCM = 112477450032/2676
LCM = 42031932
Thus, we can understand that the LCM of 556,452,669,669 is 42031932.
