Given numbers are 440,237,253,374,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,237,253,374,721 is 29397679080.
Find LCM of 440,237,253,374,721 with Prime Factorization
| 2 | 440, 237, 253, 374, 721 |
| 11 | 220, 237, 253, 187, 721 |
| 20, 237, 23, 17, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 20 x 237 x 23 x 17 x 721 = 29397679080
Therefore, the lowest common multiple of 440,237,253,374,721 is 29397679080.
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.
440 x 237 x 253 x 374 x 721 = 7114238337360
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
237 : 1, 3, 79, 237
253 : 1, 11, 23, 253
374 : 1, 2, 11, 17, 22, 34, 187, 374
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,237,253,374,721, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
237:3x 79
253:11x 23
374:2x 11x 17
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 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 7114238337360/(1x242)
LCM = 7114238337360/242
LCM = 29397679080
Thus, we can understand that the LCM of 440,237,253,374,721 is 29397679080.
