Given numbers are 699,190,380,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,190,380,620 is 8234220.
Find LCM of 699,190,380,620 with Prime Factorization
| 2 | 699, 190, 380, 620 |
| 2 | 699, 95, 190, 310 |
| 5 | 699, 95, 95, 155 |
| 19 | 699, 19, 19, 31 |
| 699, 1, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 699 x 1 x 1 x 31 = 8234220
Therefore, the lowest common multiple of 699,190,380,620 is 8234220.
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 190 x 380 x 620 = 31290036000
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
190 : 1, 2, 5, 10, 19, 38, 95, 190
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,190,380,620, is 1.
Now, the common factors can be found like this.
699:3x 233
190:2x 5x 19
380:2x 2x 5x 19
620:2x 2x 5x 31
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 5x 5x 19 = 3800
Therefore, the value for common factors is 3800.
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 = 31290036000/(1x3800)
LCM = 31290036000/3800
LCM = 8234220
Thus, we can understand that the LCM of 699,190,380,620 is 8234220.
