Given numbers are 699,690,139,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,690,139,170 is 379899510.
Find LCM of 699,690,139,170 with Prime Factorization
| 2 | 699, 690, 139, 170 |
| 3 | 699, 345, 139, 85 |
| 5 | 233, 115, 139, 85 |
| 233, 23, 139, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 233 x 23 x 139 x 17 = 379899510
Therefore, the lowest common multiple of 699,690,139,170 is 379899510.
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 690 x 139 x 170 = 11396985300
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
139 : 1, 139
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,690,139,170, is 1.
Now, the common factors can be found like this.
699:3x 233
690:2x 3x 5x 23
139:139
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 11396985300/(1x30)
LCM = 11396985300/30
LCM = 379899510
Thus, we can understand that the LCM of 699,690,139,170 is 379899510.
