Given numbers are 556,695,658,948
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,695,658,948 is 216764940.
Find LCM of 556,695,658,948 with Prime Factorization
| 2 | 556, 695, 658, 948 |
| 2 | 278, 695, 329, 474 |
| 139 | 139, 695, 329, 237 |
| 1, 5, 329, 237 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 1 x 5 x 329 x 237 = 216764940
Therefore, the lowest common multiple of 556,695,658,948 is 216764940.
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 695 x 658 x 948 = 241042613280
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
695 : 1, 5, 139, 695
658 : 1, 2, 7, 14, 47, 94, 329, 658
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,695,658,948, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
695:5x 139
658:2x 7x 47
948:2x 2x 3x 79
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 139 = 1112
Therefore, the value for common factors is 1112.
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 = 241042613280/(1x1112)
LCM = 241042613280/1112
LCM = 216764940
Thus, we can understand that the LCM of 556,695,658,948 is 216764940.
