Given numbers are 392,785,865,718,699
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,785,865,718,699 is 13358984661960.
Find LCM of 392,785,865,718,699 with Prime Factorization
| 2 | 392, 785, 865, 718, 699 |
| 5 | 196, 785, 865, 359, 699 |
| 196, 157, 173, 359, 699 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 196 x 157 x 173 x 359 x 699 = 13358984661960
Therefore, the lowest common multiple of 392,785,865,718,699 is 13358984661960.
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.
392 x 785 x 865 x 718 x 699 = 133589846619600
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
785 : 1, 5, 157, 785
865 : 1, 5, 173, 865
718 : 1, 2, 359, 718
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,785,865,718,699, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
785:5x 157
865:5x 173
718:2x 359
699:3x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 133589846619600/(1x10)
LCM = 133589846619600/10
LCM = 13358984661960
Thus, we can understand that the LCM of 392,785,865,718,699 is 13358984661960.
