The LCM of 672,608,243,980 is 36197280.
Find LCM of 672,608,243,980 with Prime Factorization
| 2 | 672, 608, 243, 980 |
| 2 | 336, 304, 243, 490 |
| 2 | 168, 152, 243, 245 |
| 2 | 84, 76, 243, 245 |
| 2 | 42, 38, 243, 245 |
| 3 | 21, 19, 243, 245 |
| 7 | 7, 19, 81, 245 |
| 1, 19, 81, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 7 x 1 x 19 x 81 x 35 = 36197280
Therefore, the lowest common multiple of 672,608,243,980 is 36197280.
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 608 x 243 x 980 = 97298288640
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
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
243 : 1, 3, 9, 27, 81, 243
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,608,243,980, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
608:2x 2x 2x 2x 2x 19
243:3x 3x 3x 3x 3
980:2x 2x 5x 7x 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 2x 2x 3x 7 = 2688
Therefore, the value for common factors is 2688.
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 = 97298288640/(1x2688)
LCM = 97298288640/2688
LCM = 36197280
Thus, we can understand that the LCM of 672,608,243,980 is 36197280.
