Given numbers are 158,570,836,778,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 158,570,836,778,712 is 68595279720.
Find LCM of 158,570,836,778,712 with Prime Factorization
| 2 | 158, 570, 836, 778, 712 |
| 2 | 79, 285, 418, 389, 356 |
| 19 | 79, 285, 209, 389, 178 |
| 79, 15, 11, 389, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 79 x 15 x 11 x 389 x 178 = 68595279720
Therefore, the lowest common multiple of 158,570,836,778,712 is 68595279720.
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.
158 x 570 x 836 x 778 x 712 = 41705930069760
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.
158 : 1, 2, 79, 158
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
778 : 1, 2, 389, 778
712 : 1, 2, 4, 8, 89, 178, 356, 712
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,570,836,778,712, is 2.
Now, the common factors can be found like this.
158:2x 79
570:2x 3x 5x 19
836:2x 2x 11x 19
778:2x 389
712:2x 2x 2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 41705930069760/(2x304)
LCM = 41705930069760/608
LCM = 68595279720
Thus, we can understand that the LCM of 158,570,836,778,712 is 68595279720.
