Given numbers are 748,706,671,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 748,706,671,863 is 13900068292.
Find LCM of 748,706,671,863 with Prime Factorization
| 2 | 748, 706, 671, 863 |
| 11 | 374, 353, 671, 863 |
| 34, 353, 61, 863 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 34 x 353 x 61 x 863 = 13900068292
Therefore, the lowest common multiple of 748,706,671,863 is 13900068292.
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.
748 x 706 x 671 x 863 = 305801502424
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
706 : 1, 2, 353, 706
671 : 1, 11, 61, 671
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,706,671,863, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
706:2x 353
671:11x 61
863:863
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 305801502424/(1x22)
LCM = 305801502424/22
LCM = 13900068292
Thus, we can understand that the LCM of 748,706,671,863 is 13900068292.
