Given numbers are 699,978,312,124,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,978,312,124,160 is 7346657760.
Find LCM of 699,978,312,124,160 with Prime Factorization
| 2 | 699, 978, 312, 124, 160 |
| 2 | 699, 489, 156, 62, 80 |
| 2 | 699, 489, 78, 31, 40 |
| 3 | 699, 489, 39, 31, 20 |
| 233, 163, 13, 31, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 233 x 163 x 13 x 31 x 20 = 7346657760
Therefore, the lowest common multiple of 699,978,312,124,160 is 7346657760.
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.
699 x 978 x 312 x 124 x 160 = 4231674869760
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.
699 : 1, 3, 233, 699
978 : 1, 2, 3, 6, 163, 326, 489, 978
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
124 : 1, 2, 4, 31, 62, 124
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,978,312,124,160, is 1.
Now, the common factors can be found like this.
699:3x 233
978:2x 3x 163
312:2x 2x 2x 3x 13
124:2x 2x 31
160:2x 2x 2x 2x 2x 5
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 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 4231674869760/(1x576)
LCM = 4231674869760/576
LCM = 7346657760
Thus, we can understand that the LCM of 699,978,312,124,160 is 7346657760.
