Given numbers are 689,195,624,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,195,624,118 is 9756240.
Find LCM of 689,195,624,118 with Prime Factorization
| 2 | 689, 195, 624, 118 |
| 3 | 689, 195, 312, 59 |
| 13 | 689, 65, 104, 59 |
| 53, 5, 8, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 53 x 5 x 8 x 59 = 9756240
Therefore, the lowest common multiple of 689,195,624,118 is 9756240.
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.
689 x 195 x 624 x 118 = 9892827360
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.
689 : 1, 13, 53, 689
195 : 1, 3, 5, 13, 15, 39, 65, 195
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,195,624,118, is 1.
Now, the common factors can be found like this.
689:13x 53
195:3x 5x 13
624:2x 2x 2x 2x 3x 13
118:2x 59
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 13x 13 = 1014
Therefore, the value for common factors is 1014.
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 = 9892827360/(1x1014)
LCM = 9892827360/1014
LCM = 9756240
Thus, we can understand that the LCM of 689,195,624,118 is 9756240.
