Given numbers are 556,412,948,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,412,948,721 is 95007612.
Find LCM of 556,412,948,721 with Prime Factorization
| 2 | 556, 412, 948, 721 |
| 2 | 278, 206, 474, 721 |
| 103 | 139, 103, 237, 721 |
| 139, 1, 237, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 103 x 139 x 1 x 237 x 7 = 95007612
Therefore, the lowest common multiple of 556,412,948,721 is 95007612.
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 412 x 948 x 721 = 156572544576
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
412 : 1, 2, 4, 103, 206, 412
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,412,948,721, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
412:2x 2x 103
948:2x 2x 3x 79
721:7x 103
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 2x 2x 103 = 1648
Therefore, the value for common factors is 1648.
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 = 156572544576/(1x1648)
LCM = 156572544576/1648
LCM = 95007612
Thus, we can understand that the LCM of 556,412,948,721 is 95007612.
