Given numbers are 788,915,839,870,613
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,915,839,870,613 is 10753943361060.
Find LCM of 788,915,839,870,613 with Prime Factorization
| 2 | 788, 915, 839, 870, 613 |
| 3 | 394, 915, 839, 435, 613 |
| 5 | 394, 305, 839, 145, 613 |
| 394, 61, 839, 29, 613 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 394 x 61 x 839 x 29 x 613 = 10753943361060
Therefore, the lowest common multiple of 788,915,839,870,613 is 10753943361060.
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.
788 x 915 x 839 x 870 x 613 = 322618300831800
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.
788 : 1, 2, 4, 197, 394, 788
915 : 1, 3, 5, 15, 61, 183, 305, 915
839 : 1, 839
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
613 : 1, 613
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,915,839,870,613, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
915:3x 5x 61
839:839
870:2x 3x 5x 29
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.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 322618300831800/(1x30)
LCM = 322618300831800/30
LCM = 10753943361060
Thus, we can understand that the LCM of 788,915,839,870,613 is 10753943361060.
