Find LCM of 251,352,456,355,120 with Prime Factorization
| 2 | 251, 352, 456, 355, 120 |
| 2 | 251, 176, 228, 355, 60 |
| 2 | 251, 88, 114, 355, 30 |
| 3 | 251, 44, 57, 355, 15 |
| 5 | 251, 44, 19, 355, 5 |
| 251, 44, 19, 71, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 251 x 44 x 19 x 71 x 1 = 1787802720
Therefore, the lowest common multiple of 251,352,456,355,120 is 1787802720.
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.
251 x 352 x 456 x 355 x 120 = 1716290611200
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.
251 : 1, 251
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
355 : 1, 5, 71, 355
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,352,456,355,120, is 1.
Now, the common factors can be found like this.
251:251
352:2x 2x 2x 2x 2x 11
456:2x 2x 2x 3x 19
355:5x 71
120:2x 2x 2x 3x 5
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 2x 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 1716290611200/(1x960)
LCM = 1716290611200/960
LCM = 1787802720
Thus, we can understand that the LCM of 251,352,456,355,120 is 1787802720.
