The LCM of 365,168,812,820,390 is 947823240.
Find LCM of 365,168,812,820,390 with Prime Factorization
| 2 | 365, 168, 812, 820, 390 |
| 2 | 365, 84, 406, 410, 195 |
| 3 | 365, 42, 203, 205, 195 |
| 5 | 365, 14, 203, 205, 65 |
| 7 | 73, 14, 203, 41, 13 |
| 73, 2, 29, 41, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 73 x 2 x 29 x 41 x 13 = 947823240
Therefore, the lowest common multiple of 365,168,812,820,390 is 947823240.
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.
365 x 168 x 812 x 820 x 390 = 15923430432000
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.
365 : 1, 5, 73, 365
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 365,168,812,820,390, is 1.
Now, the common factors can be found like this.
365:5x 73
168:2x 2x 2x 3x 7
812:2x 2x 7x 29
820:2x 2x 5x 41
390:2x 3x 5x 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 2x 2x 2x 3x 5x 5x 7 = 16800
Therefore, the value for common factors is 16800.
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 = 15923430432000/(1x16800)
LCM = 15923430432000/16800
LCM = 947823240
Thus, we can understand that the LCM of 365,168,812,820,390 is 947823240.
