Given numbers are 138,124,545,765,795
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 138,124,545,765,795 is 12604143060.
Find LCM of 138,124,545,765,795 with Prime Factorization
| 2 | 138, 124, 545, 765, 795 |
| 3 | 69, 62, 545, 765, 795 |
| 5 | 23, 62, 545, 255, 265 |
| 23, 62, 109, 51, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 62 x 109 x 51 x 53 = 12604143060
Therefore, the lowest common multiple of 138,124,545,765,795 is 12604143060.
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.
138 x 124 x 545 x 765 x 795 = 5671864377000
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
124 : 1, 2, 4, 31, 62, 124
545 : 1, 5, 109, 545
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
795 : 1, 3, 5, 15, 53, 159, 265, 795
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,124,545,765,795, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
124:2x 2x 31
545:5x 109
765:3x 3x 5x 17
795:3x 5x 53
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 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 5671864377000/(1x450)
LCM = 5671864377000/450
LCM = 12604143060
Thus, we can understand that the LCM of 138,124,545,765,795 is 12604143060.
