Given numbers are 667,103,638,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,103,638,145 is 7557110.
Find LCM of 667,103,638,145 with Prime Factorization
29 | 667, 103, 638, 145 |
23, 103, 22, 5 |
Multiply the prime numbers at the bottom and the left side.
29 x 23 x 103 x 22 x 5 = 7557110
Therefore, the lowest common multiple of 667,103,638,145 is 7557110.
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.
667 x 103 x 638 x 145 = 6355529510
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.
667 : 1, 23, 29, 667
103 : 1, 103
638 : 1, 2, 11, 22, 29, 58, 319, 638
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,103,638,145, is 1.
Now, the common factors can be found like this.
667:23x 29
103:103
638:2x 11x 29
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29x 29 = 841
Therefore, the value for common factors is 841.
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 = 6355529510/(1x841)
LCM = 6355529510/841
LCM = 7557110
Thus, we can understand that the LCM of 667,103,638,145 is 7557110.
