The LCM of 672,861,434,273 is 11103456.
Find LCM of 672,861,434,273 with Prime Factorization
| 2 | 672, 861, 434, 273 |
| 3 | 336, 861, 217, 273 |
| 7 | 112, 287, 217, 91 |
| 16, 41, 31, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 16 x 41 x 31 x 13 = 11103456
Therefore, the lowest common multiple of 672,861,434,273 is 11103456.
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 861 x 434 x 273 = 68552737344
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
434 : 1, 2, 7, 14, 31, 62, 217, 434
273 : 1, 3, 7, 13, 21, 39, 91, 273
7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,861,434,273, is 7.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
861:3x 7x 41
434:2x 7x 31
273:3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 68552737344/(7x882)
LCM = 68552737344/6174
LCM = 11103456
Thus, we can understand that the LCM of 672,861,434,273 is 11103456.
