Given numbers are 556,221,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,221,702 is 3317652.
Find LCM of 556,221,702 with Prime Factorization
| 2 | 556, 221, 702 |
| 13 | 278, 221, 351 |
| 278, 17, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 278 x 17 x 27 = 3317652
Therefore, the lowest common multiple of 556,221,702 is 3317652.
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 221 x 702 = 86258952
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
221 : 1, 13, 17, 221
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,221,702, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
221:13x 17
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 86258952/(1x26)
LCM = 86258952/26
LCM = 3317652
Thus, we can understand that the LCM of 556,221,702 is 3317652.
