Given numbers are 672,728,939,178,610
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,728,939,178,610 is 74224419360.
Find LCM of 672,728,939,178,610 with Prime Factorization
| 2 | 672, 728, 939, 178, 610 |
| 2 | 336, 364, 939, 89, 305 |
| 2 | 168, 182, 939, 89, 305 |
| 3 | 84, 91, 939, 89, 305 |
| 7 | 28, 91, 313, 89, 305 |
| 4, 13, 313, 89, 305 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 4 x 13 x 313 x 89 x 305 = 74224419360
Therefore, the lowest common multiple of 672,728,939,178,610 is 74224419360.
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 728 x 939 x 178 x 610 = 49878809809920
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
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
939 : 1, 3, 313, 939
178 : 1, 2, 89, 178
610 : 1, 2, 5, 10, 61, 122, 305, 610
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,728,939,178,610, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
728:2x 2x 2x 7x 13
939:3x 313
178:2x 89
610:2x 5x 61
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 7 = 672
Therefore, the value for common factors is 672.
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 = 49878809809920/(1x672)
LCM = 49878809809920/672
LCM = 74224419360
Thus, we can understand that the LCM of 672,728,939,178,610 is 74224419360.
