Given numbers are 609,847,309,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,847,309,770 is 75899670.
Find LCM of 609,847,309,770 with Prime Factorization
| 3 | 609, 847, 309, 770 |
| 7 | 203, 847, 103, 770 |
| 11 | 29, 121, 103, 110 |
| 29, 11, 103, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 29 x 11 x 103 x 10 = 75899670
Therefore, the lowest common multiple of 609,847,309,770 is 75899670.
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.
609 x 847 x 309 x 770 = 122729766390
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
847 : 1, 7, 11, 77, 121, 847
309 : 1, 3, 103, 309
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,847,309,770, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
847:7x 11x 11
309:3x 103
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 11 = 1617
Therefore, the value for common factors is 1617.
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 = 122729766390/(1x1617)
LCM = 122729766390/1617
LCM = 75899670
Thus, we can understand that the LCM of 609,847,309,770 is 75899670.
