Find LCM of 480,689,120,649,242 with Prime Factorization
| 2 | 480, 689, 120, 649, 242 |
| 2 | 240, 689, 60, 649, 121 |
| 2 | 120, 689, 30, 649, 121 |
| 3 | 60, 689, 15, 649, 121 |
| 5 | 20, 689, 5, 649, 121 |
| 11 | 4, 689, 1, 649, 121 |
| 4, 689, 1, 59, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 4 x 689 x 1 x 59 x 11 = 2361010080
Therefore, the lowest common multiple of 480,689,120,649,242 is 2361010080.
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.
480 x 689 x 120 x 649 x 242 = 6233066611200
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.
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
689 : 1, 13, 53, 689
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
649 : 1, 11, 59, 649
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 480,689,120,649,242, is 1.
Now, the common factors can be found like this.
480:2x 2x 2x 2x 2x 3x 5
689:13x 53
120:2x 2x 2x 3x 5
649:11x 59
242:2x 11x 11
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 3x 5x 11 = 2640
Therefore, the value for common factors is 2640.
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 = 6233066611200/(1x2640)
LCM = 6233066611200/2640
LCM = 2361010080
Thus, we can understand that the LCM of 480,689,120,649,242 is 2361010080.
