Given numbers are 556,974,221,193
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,974,221,193 is 11549238116.
Find LCM of 556,974,221,193 with Prime Factorization
| 2 | 556, 974, 221, 193 |
| 278, 487, 221, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 278 x 487 x 221 x 193 = 11549238116
Therefore, the lowest common multiple of 556,974,221,193 is 11549238116.
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 974 x 221 x 193 = 23098476232
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
974 : 1, 2, 487, 974
221 : 1, 13, 17, 221
193 : 1, 193
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,974,221,193, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
974:2x 487
221:13x 17
193:193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 23098476232/(1x2)
LCM = 23098476232/2
LCM = 11549238116
Thus, we can understand that the LCM of 556,974,221,193 is 11549238116.
