Given numbers are 220,435,227,860,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,435,227,860,721 is 134701214340.
Find LCM of 220,435,227,860,721 with Prime Factorization
| 2 | 220, 435, 227, 860, 721 |
| 2 | 110, 435, 227, 430, 721 |
| 5 | 55, 435, 227, 215, 721 |
| 11, 87, 227, 43, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 87 x 227 x 43 x 721 = 134701214340
Therefore, the lowest common multiple of 220,435,227,860,721 is 134701214340.
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.
220 x 435 x 227 x 860 x 721 = 13470121434000
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
435 : 1, 3, 5, 15, 29, 87, 145, 435
227 : 1, 227
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,435,227,860,721, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
435:3x 5x 29
227:227
860:2x 2x 5x 43
721:7x 103
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 13470121434000/(1x100)
LCM = 13470121434000/100
LCM = 134701214340
Thus, we can understand that the LCM of 220,435,227,860,721 is 134701214340.
