Find LCM of 254,351,990,786,278 with Prime Factorization
2 | 254, 351, 990, 786, 278 |
3 | 127, 351, 495, 393, 139 |
3 | 127, 117, 165, 131, 139 |
127, 39, 55, 131, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 127 x 39 x 55 x 131 x 139 = 89287285230
Therefore, the lowest common multiple of 254,351,990,786,278 is 89287285230.
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.
254 x 351 x 990 x 786 x 278 = 19286053609680
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.
254 : 1, 2, 127, 254
351 : 1, 3, 9, 13, 27, 39, 117, 351
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
786 : 1, 2, 3, 6, 131, 262, 393, 786
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,351,990,786,278, is 1.
Now, the common factors can be found like this.
254:2x 127
351:3x 3x 3x 13
990:2x 3x 3x 5x 11
786:2x 3x 131
278:2x 139
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 19286053609680/(1x216)
LCM = 19286053609680/216
LCM = 89287285230
Thus, we can understand that the LCM of 254,351,990,786,278 is 89287285230.
