Given numbers are 155,527,221,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,527,221,767 is 2021045.
Find LCM of 155,527,221,767 with Prime Factorization
| 13 | 155, 527, 221, 767 |
| 17 | 155, 527, 17, 59 |
| 31 | 155, 31, 1, 59 |
| 5, 1, 1, 59 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 31 x 5 x 1 x 1 x 59 = 2021045
Therefore, the lowest common multiple of 155,527,221,767 is 2021045.
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.
155 x 527 x 221 x 767 = 13846179295
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.
155 : 1, 5, 31, 155
527 : 1, 17, 31, 527
221 : 1, 13, 17, 221
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,527,221,767, is 1.
Now, the common factors can be found like this.
155:5x 31
527:17x 31
221:13x 17
767:13x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17x 31 = 6851
Therefore, the value for common factors is 6851.
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 = 13846179295/(1x6851)
LCM = 13846179295/6851
LCM = 2021045
Thus, we can understand that the LCM of 155,527,221,767 is 2021045.
