Given numbers are 787,280,446,613
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,280,446,613 is 30122991640.
Find LCM of 787,280,446,613 with Prime Factorization
| 2 | 787, 280, 446, 613 |
| 787, 140, 223, 613 |
Multiply the prime numbers at the bottom and the left side.
2 x 787 x 140 x 223 x 613 = 30122991640
Therefore, the lowest common multiple of 787,280,446,613 is 30122991640.
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 280 x 446 x 613 = 60245983280
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
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
446 : 1, 2, 223, 446
613 : 1, 613
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,280,446,613, is 1.
Now, the common factors can be found like this.
787:787
280:2x 2x 2x 5x 7
446:2x 223
613:613
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 60245983280/(1x2)
LCM = 60245983280/2
LCM = 30122991640
Thus, we can understand that the LCM of 787,280,446,613 is 30122991640.
