Given numbers are 290,790,649,711
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,790,649,711 is 133817310.
Find LCM of 290,790,649,711 with Prime Factorization
| 2 | 290, 790, 649, 711 |
| 5 | 145, 395, 649, 711 |
| 79 | 29, 79, 649, 711 |
| 29, 1, 649, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 79 x 29 x 1 x 649 x 9 = 133817310
Therefore, the lowest common multiple of 290,790,649,711 is 133817310.
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.
290 x 790 x 649 x 711 = 105715674900
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
790 : 1, 2, 5, 10, 79, 158, 395, 790
649 : 1, 11, 59, 649
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,790,649,711, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
790:2x 5x 79
649:11x 59
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 79 = 790
Therefore, the value for common factors is 790.
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 = 105715674900/(1x790)
LCM = 105715674900/790
LCM = 133817310
Thus, we can understand that the LCM of 290,790,649,711 is 133817310.
