Find LCM of 628,819,254,180,560 with Prime Factorization
| 2 | 628, 819, 254, 180, 560 |
| 2 | 314, 819, 127, 90, 280 |
| 3 | 157, 819, 127, 45, 140 |
| 3 | 157, 273, 127, 15, 140 |
| 5 | 157, 91, 127, 5, 140 |
| 7 | 157, 91, 127, 1, 28 |
| 157, 13, 127, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 7 x 157 x 13 x 127 x 1 x 4 = 1306403280
Therefore, the lowest common multiple of 628,819,254,180,560 is 1306403280.
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.
628 x 819 x 254 x 180 x 560 = 13168545062400
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.
628 : 1, 2, 4, 157, 314, 628
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
254 : 1, 2, 127, 254
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,819,254,180,560, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
819:3x 3x 7x 13
254:2x 127
180:2x 2x 3x 3x 5
560:2x 2x 2x 2x 5x 7
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 3x 5x 7 = 10080
Therefore, the value for common factors is 10080.
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 = 13168545062400/(1x10080)
LCM = 13168545062400/10080
LCM = 1306403280
Thus, we can understand that the LCM of 628,819,254,180,560 is 1306403280.
