Given numbers are 787,445,549,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,445,549,549 is 192268035.
Find LCM of 787,445,549,549 with Prime Factorization
| 3 | 787, 445, 549, 549 |
| 3 | 787, 445, 183, 183 |
| 61 | 787, 445, 61, 61 |
| 787, 445, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 61 x 787 x 445 x 1 x 1 = 192268035
Therefore, the lowest common multiple of 787,445,549,549 is 192268035.
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.
787 x 445 x 549 x 549 = 105555151215
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.
787 : 1, 787
445 : 1, 5, 89, 445
549 : 1, 3, 9, 61, 183, 549
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,445,549,549, is 1.
Now, the common factors can be found like this.
787:787
445:5x 89
549:3x 3x 61
549:3x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 61 = 549
Therefore, the value for common factors is 549.
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 = 105555151215/(1x549)
LCM = 105555151215/549
LCM = 192268035
Thus, we can understand that the LCM of 787,445,549,549 is 192268035.
