Find LCM of 672,260,221,480 with Prime Factorization
| 2 | 672, 260, 221, 480 |
| 2 | 336, 130, 221, 240 |
| 2 | 168, 65, 221, 120 |
| 2 | 84, 65, 221, 60 |
| 2 | 42, 65, 221, 30 |
| 3 | 21, 65, 221, 15 |
| 5 | 7, 65, 221, 5 |
| 13 | 7, 13, 221, 1 |
| 7, 1, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 13 x 7 x 1 x 17 x 1 = 742560
Therefore, the lowest common multiple of 672,260,221,480 is 742560.
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.
672 x 260 x 221 x 480 = 18534297600
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
221 : 1, 13, 17, 221
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,260,221,480, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
260:2x 2x 5x 13
221:13x 17
480:2x 2x 2x 2x 2x 3x 5
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 2x 2x 3x 5x 13 = 24960
Therefore, the value for common factors is 24960.
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 = 18534297600/(1x24960)
LCM = 18534297600/24960
LCM = 742560
Thus, we can understand that the LCM of 672,260,221,480 is 742560.
