Given numbers are 822,340,492,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,340,492,656 is 22917360.
Find LCM of 822,340,492,656 with Prime Factorization
2 | 822, 340, 492, 656 |
2 | 411, 170, 246, 328 |
3 | 411, 85, 123, 164 |
41 | 137, 85, 41, 164 |
137, 85, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 137 x 85 x 1 x 4 = 22917360
Therefore, the lowest common multiple of 822,340,492,656 is 22917360.
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 340 x 492 x 656 = 90202728960
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,340,492,656, is 2.
Now, the common factors can be found like this.
822:2x 3x 137
340:2x 2x 5x 17
492:2x 2x 3x 41
656:2x 2x 2x 2x 41
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 41 = 1968
Therefore, the value for common factors is 1968.
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 = 90202728960/(2x1968)
LCM = 90202728960/3936
LCM = 22917360
Thus, we can understand that the LCM of 822,340,492,656 is 22917360.
