Given numbers are 869,617,682,719,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,617,682,719,620 is 239015199940.
Find LCM of 869,617,682,719,620 with Prime Factorization
| 2 | 869, 617, 682, 719, 620 |
| 11 | 869, 617, 341, 719, 310 |
| 31 | 79, 617, 31, 719, 310 |
| 79, 617, 1, 719, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 31 x 79 x 617 x 1 x 719 x 10 = 239015199940
Therefore, the lowest common multiple of 869,617,682,719,620 is 239015199940.
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.
869 x 617 x 682 x 719 x 620 = 163008366359080
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.
869 : 1, 11, 79, 869
617 : 1, 617
682 : 1, 2, 11, 22, 31, 62, 341, 682
719 : 1, 719
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 869,617,682,719,620, is 1.
Now, the common factors can be found like this.
869:11x 79
617:617
682:2x 11x 31
719:719
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 11x 31 = 682
Therefore, the value for common factors is 682.
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 = 163008366359080/(1x682)
LCM = 163008366359080/682
LCM = 239015199940
Thus, we can understand that the LCM of 869,617,682,719,620 is 239015199940.
