Given numbers are 223,242,220,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 223,242,220,428 is 57743620.
Find LCM of 223,242,220,428 with Prime Factorization
| 2 | 223, 242, 220, 428 |
| 2 | 223, 121, 110, 214 |
| 11 | 223, 121, 55, 107 |
| 223, 11, 5, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 223 x 11 x 5 x 107 = 57743620
Therefore, the lowest common multiple of 223,242,220,428 is 57743620.
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.
223 x 242 x 220 x 428 = 5081438560
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.
223 : 1, 223
242 : 1, 2, 11, 22, 121, 242
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,242,220,428, is 1.
Now, the common factors can be found like this.
223:223
242:2x 11x 11
220:2x 2x 5x 11
428:2x 2x 107
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 11 = 88
Therefore, the value for common factors is 88.
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 = 5081438560/(1x88)
LCM = 5081438560/88
LCM = 57743620
Thus, we can understand that the LCM of 223,242,220,428 is 57743620.
