Given numbers are 635,170,699,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,170,699,856 is 6459123480.
Find LCM of 635,170,699,856 with Prime Factorization
| 2 | 635, 170, 699, 856 |
| 5 | 635, 85, 699, 428 |
| 127, 17, 699, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 127 x 17 x 699 x 428 = 6459123480
Therefore, the lowest common multiple of 635,170,699,856 is 6459123480.
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.
635 x 170 x 699 x 856 = 64591234800
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.
635 : 1, 5, 127, 635
170 : 1, 2, 5, 10, 17, 34, 85, 170
699 : 1, 3, 233, 699
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,170,699,856, is 1.
Now, the common factors can be found like this.
635:5x 127
170:2x 5x 17
699:3x 233
856:2x 2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 64591234800/(1x10)
LCM = 64591234800/10
LCM = 6459123480
Thus, we can understand that the LCM of 635,170,699,856 is 6459123480.
