Given numbers are 790,695,542,480
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,695,542,480 is 1428408480.
Find LCM of 790,695,542,480 with Prime Factorization
| 2 | 790, 695, 542, 480 |
| 5 | 395, 695, 271, 240 |
| 79, 139, 271, 48 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 139 x 271 x 48 = 1428408480
Therefore, the lowest common multiple of 790,695,542,480 is 1428408480.
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.
790 x 695 x 542 x 480 = 142840848000
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
695 : 1, 5, 139, 695
542 : 1, 2, 271, 542
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,695,542,480, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
695:5x 139
542:2x 271
480:2x 2x 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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 142840848000/(1x100)
LCM = 142840848000/100
LCM = 1428408480
Thus, we can understand that the LCM of 790,695,542,480 is 1428408480.
