Given numbers are 634,840,672,168,962
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,840,672,168,962 is 512322720.
Find LCM of 634,840,672,168,962 with Prime Factorization
| 2 | 634, 840, 672, 168, 962 |
| 2 | 317, 420, 336, 84, 481 |
| 2 | 317, 210, 168, 42, 481 |
| 3 | 317, 105, 84, 21, 481 |
| 7 | 317, 35, 28, 7, 481 |
| 317, 5, 4, 1, 481 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 317 x 5 x 4 x 1 x 481 = 512322720
Therefore, the lowest common multiple of 634,840,672,168,962 is 512322720.
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.
634 x 840 x 672 x 168 x 962 = 57839185797120
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.
634 : 1, 2, 317, 634
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
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
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
962 : 1, 2, 13, 26, 37, 74, 481, 962
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,840,672,168,962, is 2.
Now, the common factors can be found like this.
634:2x 317
840:2x 2x 2x 3x 5x 7
672:2x 2x 2x 2x 2x 3x 7
168:2x 2x 2x 3x 7
962:2x 13x 37
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 3x 7x 7 = 56448
Therefore, the value for common factors is 56448.
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 = 57839185797120/(2x56448)
LCM = 57839185797120/112896
LCM = 512322720
Thus, we can understand that the LCM of 634,840,672,168,962 is 512322720.
