Given numbers are 705,272,578,185
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,272,578,185 is 120617040.
Find LCM of 705,272,578,185 with Prime Factorization
| 2 | 705, 272, 578, 185 |
| 5 | 705, 136, 289, 185 |
| 17 | 141, 136, 289, 37 |
| 141, 8, 17, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 141 x 8 x 17 x 37 = 120617040
Therefore, the lowest common multiple of 705,272,578,185 is 120617040.
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.
705 x 272 x 578 x 185 = 20504896800
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
578 : 1, 2, 17, 34, 289, 578
185 : 1, 5, 37, 185
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,272,578,185, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
272:2x 2x 2x 2x 17
578:2x 17x 17
185:5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 20504896800/(1x170)
LCM = 20504896800/170
LCM = 120617040
Thus, we can understand that the LCM of 705,272,578,185 is 120617040.
