Given numbers are 674,822,156,961,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,822,156,961,660 is 380680949220.
Find LCM of 674,822,156,961,660 with Prime Factorization
| 2 | 674, 822, 156, 961, 660 |
| 2 | 337, 411, 78, 961, 330 |
| 3 | 337, 411, 39, 961, 165 |
| 337, 137, 13, 961, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 337 x 137 x 13 x 961 x 55 = 380680949220
Therefore, the lowest common multiple of 674,822,156,961,660 is 380680949220.
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.
674 x 822 x 156 x 961 x 660 = 54818056687680
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.
674 : 1, 2, 337, 674
822 : 1, 2, 3, 6, 137, 274, 411, 822
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
961 : 1, 31, 961
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,822,156,961,660, is 1.
Now, the common factors can be found like this.
674:2x 337
822:2x 3x 137
156:2x 2x 3x 13
961:31x 31
660:2x 2x 3x 5x 11
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 54818056687680/(1x144)
LCM = 54818056687680/144
LCM = 380680949220
Thus, we can understand that the LCM of 674,822,156,961,660 is 380680949220.
