Given numbers are 227,142,454,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 227,142,454,355 is 161170.
Find LCM of 227,142,454,355 with Prime Factorization
| 2 | 227, 142, 454, 355 |
| 71 | 227, 71, 227, 355 |
| 227 | 227, 1, 227, 5 |
| 1, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 227 x 1 x 1 x 1 x 5 = 161170
Therefore, the lowest common multiple of 227,142,454,355 is 161170.
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.
227 x 142 x 454 x 355 = 5195153780
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.
227 : 1, 227
142 : 1, 2, 71, 142
454 : 1, 2, 227, 454
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,142,454,355, is 1.
Now, the common factors can be found like this.
227:227
142:2x 71
454:2x 227
355:5x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71x 227 = 32234
Therefore, the value for common factors is 32234.
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 = 5195153780/(1x32234)
LCM = 5195153780/32234
LCM = 161170
Thus, we can understand that the LCM of 227,142,454,355 is 161170.
