Given numbers are 822,273,142,772,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,273,142,772,689 is 108651251436.
Find LCM of 822,273,142,772,689 with Prime Factorization
| 2 | 822, 273, 142, 772, 689 |
| 3 | 411, 273, 71, 386, 689 |
| 13 | 137, 91, 71, 386, 689 |
| 137, 7, 71, 386, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 137 x 7 x 71 x 386 x 53 = 108651251436
Therefore, the lowest common multiple of 822,273,142,772,689 is 108651251436.
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.
822 x 273 x 142 x 772 x 689 = 16949595224016
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
273 : 1, 3, 7, 13, 21, 39, 91, 273
142 : 1, 2, 71, 142
772 : 1, 2, 4, 193, 386, 772
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,273,142,772,689, is 1.
Now, the common factors can be found like this.
822:2x 3x 137
273:3x 7x 13
142:2x 71
772:2x 2x 193
689:13x 53
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 16949595224016/(1x156)
LCM = 16949595224016/156
LCM = 108651251436
Thus, we can understand that the LCM of 822,273,142,772,689 is 108651251436.
