The LCM of 361,390,746,975,286 is 2888306850.
Find LCM of 361,390,746,975,286 with Prime Factorization
| 2 | 361, 390, 746, 975, 286 |
| 3 | 361, 195, 373, 975, 143 |
| 5 | 361, 65, 373, 325, 143 |
| 13 | 361, 13, 373, 65, 143 |
| 361, 1, 373, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 361 x 1 x 373 x 5 x 11 = 2888306850
Therefore, the lowest common multiple of 361,390,746,975,286 is 2888306850.
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.
361 x 390 x 746 x 975 x 286 = 29287431459000
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.
361 : 1, 19, 361
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
746 : 1, 2, 373, 746
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,390,746,975,286, is 1.
Now, the common factors can be found like this.
361:19x 19
390:2x 3x 5x 13
746:2x 373
975:3x 5x 5x 13
286:2x 11x 13
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 3x 5x 13x 13 = 10140
Therefore, the value for common factors is 10140.
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 = 29287431459000/(1x10140)
LCM = 29287431459000/10140
LCM = 2888306850
Thus, we can understand that the LCM of 361,390,746,975,286 is 2888306850.
