Find LCM of 560,691,672,880 with Prime Factorization
| 2 | 560, 691, 672, 880 |
| 2 | 280, 691, 336, 440 |
| 2 | 140, 691, 168, 220 |
| 2 | 70, 691, 84, 110 |
| 5 | 35, 691, 42, 55 |
| 7 | 7, 691, 42, 11 |
| 1, 691, 6, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 7 x 1 x 691 x 6 x 11 = 25539360
Therefore, the lowest common multiple of 560,691,672,880 is 25539360.
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.
560 x 691 x 672 x 880 = 228832665600
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
691 : 1, 691
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
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,691,672,880, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
691:691
672:2x 2x 2x 2x 2x 3x 7
880:2x 2x 2x 2x 5x 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 2x 2x 2x 2x 5x 7 = 8960
Therefore, the value for common factors is 8960.
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 = 228832665600/(1x8960)
LCM = 228832665600/8960
LCM = 25539360
Thus, we can understand that the LCM of 560,691,672,880 is 25539360.
