Given numbers are 724,238,724,202,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,238,724,202,221 is 113122828.
Find LCM of 724,238,724,202,221 with Prime Factorization
| 2 | 724, 238, 724, 202, 221 |
| 2 | 362, 119, 362, 101, 221 |
| 17 | 181, 119, 181, 101, 221 |
| 181 | 181, 7, 181, 101, 13 |
| 1, 7, 1, 101, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 181 x 1 x 7 x 1 x 101 x 13 = 113122828
Therefore, the lowest common multiple of 724,238,724,202,221 is 113122828.
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.
724 x 238 x 724 x 202 x 221 = 5569263068096
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.
724 : 1, 2, 4, 181, 362, 724
238 : 1, 2, 7, 14, 17, 34, 119, 238
724 : 1, 2, 4, 181, 362, 724
202 : 1, 2, 101, 202
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,238,724,202,221, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
238:2x 7x 17
724:2x 2x 181
202:2x 101
221:13x 17
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 2x 17x 181 = 49232
Therefore, the value for common factors is 49232.
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 = 5569263068096/(1x49232)
LCM = 5569263068096/49232
LCM = 113122828
Thus, we can understand that the LCM of 724,238,724,202,221 is 113122828.
