Given numbers are 355,320,154,363,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,320,154,363,170 is 981435840.
Find LCM of 355,320,154,363,170 with Prime Factorization
| 2 | 355, 320, 154, 363, 170 |
| 5 | 355, 160, 77, 363, 85 |
| 11 | 71, 32, 77, 363, 17 |
| 71, 32, 7, 33, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 71 x 32 x 7 x 33 x 17 = 981435840
Therefore, the lowest common multiple of 355,320,154,363,170 is 981435840.
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.
355 x 320 x 154 x 363 x 170 = 1079579424000
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.
355 : 1, 5, 71, 355
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
154 : 1, 2, 7, 11, 14, 22, 77, 154
363 : 1, 3, 11, 33, 121, 363
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,320,154,363,170, is 1.
Now, the common factors can be found like this.
355:5x 71
320:2x 2x 2x 2x 2x 2x 5
154:2x 7x 11
363:3x 11x 11
170:2x 5x 17
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 5x 11 = 1100
Therefore, the value for common factors is 1100.
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 = 1079579424000/(1x1100)
LCM = 1079579424000/1100
LCM = 981435840
Thus, we can understand that the LCM of 355,320,154,363,170 is 981435840.
