Given numbers are 607,663,689,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 607,663,689,138 is 981151158.
Find LCM of 607,663,689,138 with Prime Factorization
| 3 | 607, 663, 689, 138 |
| 13 | 607, 221, 689, 46 |
| 607, 17, 53, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 607 x 17 x 53 x 46 = 981151158
Therefore, the lowest common multiple of 607,663,689,138 is 981151158.
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.
607 x 663 x 689 x 138 = 38264895162
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.
607 : 1, 607
663 : 1, 3, 13, 17, 39, 51, 221, 663
689 : 1, 13, 53, 689
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 607,663,689,138, is 1.
Now, the common factors can be found like this.
607:607
663:3x 13x 17
689:13x 53
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 38264895162/(1x39)
LCM = 38264895162/39
LCM = 981151158
Thus, we can understand that the LCM of 607,663,689,138 is 981151158.
