Given numbers are 556,399,722,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,399,722,556 is 4215036.
Find LCM of 556,399,722,556 with Prime Factorization
| 2 | 556, 399, 722, 556 |
| 2 | 278, 399, 361, 278 |
| 19 | 139, 399, 361, 139 |
| 139 | 139, 21, 19, 139 |
| 1, 21, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 139 x 1 x 21 x 19 x 1 = 4215036
Therefore, the lowest common multiple of 556,399,722,556 is 4215036.
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 399 x 722 x 556 = 89055280608
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
399 : 1, 3, 7, 19, 21, 57, 133, 399
722 : 1, 2, 19, 38, 361, 722
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 556,399,722,556, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
399:3x 7x 19
722:2x 19x 19
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 2x 2x 19x 139 = 21128
Therefore, the value for common factors is 21128.
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 = 89055280608/(1x21128)
LCM = 89055280608/21128
LCM = 4215036
Thus, we can understand that the LCM of 556,399,722,556 is 4215036.
