Given numbers are 905,440,219,772,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,440,219,772,254 is 427500272760.
Find LCM of 905,440,219,772,254 with Prime Factorization
| 2 | 905, 440, 219, 772, 254 |
| 2 | 905, 220, 219, 386, 127 |
| 5 | 905, 110, 219, 193, 127 |
| 181, 22, 219, 193, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 181 x 22 x 219 x 193 x 127 = 427500272760
Therefore, the lowest common multiple of 905,440,219,772,254 is 427500272760.
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.
905 x 440 x 219 x 772 x 254 = 17100010910400
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.
905 : 1, 5, 181, 905
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
219 : 1, 3, 73, 219
772 : 1, 2, 4, 193, 386, 772
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,440,219,772,254, is 1.
Now, the common factors can be found like this.
905:5x 181
440:2x 2x 2x 5x 11
219:3x 73
772:2x 2x 193
254:2x 127
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 5 = 40
Therefore, the value for common factors is 40.
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 = 17100010910400/(1x40)
LCM = 17100010910400/40
LCM = 427500272760
Thus, we can understand that the LCM of 905,440,219,772,254 is 427500272760.
