Given numbers are 139,630,768,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,630,768,120 is 11208960.
Find LCM of 139,630,768,120 with Prime Factorization
| 2 | 139, 630, 768, 120 |
| 2 | 139, 315, 384, 60 |
| 2 | 139, 315, 192, 30 |
| 3 | 139, 315, 96, 15 |
| 5 | 139, 105, 32, 5 |
| 139, 21, 32, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 139 x 21 x 32 x 1 = 11208960
Therefore, the lowest common multiple of 139,630,768,120 is 11208960.
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.
139 x 630 x 768 x 120 = 8070451200
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.
139 : 1, 139
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,630,768,120, is 1.
Now, the common factors can be found like this.
139:139
630:2x 3x 3x 5x 7
768:2x 2x 2x 2x 2x 2x 2x 2x 3
120:2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 8070451200/(1x720)
LCM = 8070451200/720
LCM = 11208960
Thus, we can understand that the LCM of 139,630,768,120 is 11208960.
