Find LCM of 672,360,870,663,178 with Prime Factorization
| 2 | 672, 360, 870, 663, 178 |
| 2 | 336, 180, 435, 663, 89 |
| 2 | 168, 90, 435, 663, 89 |
| 3 | 84, 45, 435, 663, 89 |
| 5 | 28, 15, 145, 221, 89 |
| 28, 3, 29, 221, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 28 x 3 x 29 x 221 x 89 = 5749642080
Therefore, the lowest common multiple of 672,360,870,663,178 is 5749642080.
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 360 x 870 x 663 x 178 = 24838453785600
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
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
663 : 1, 3, 13, 17, 39, 51, 221, 663
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,360,870,663,178, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
360:2x 2x 2x 3x 3x 5
870:2x 3x 5x 29
663:3x 13x 17
178:2x 89
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 3x 5 = 4320
Therefore, the value for common factors is 4320.
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 = 24838453785600/(1x4320)
LCM = 24838453785600/4320
LCM = 5749642080
Thus, we can understand that the LCM of 672,360,870,663,178 is 5749642080.
