Given numbers are 855,466,796,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,466,796,980 is 7770181860.
Find LCM of 855,466,796,980 with Prime Factorization
| 2 | 855, 466, 796, 980 |
| 2 | 855, 233, 398, 490 |
| 5 | 855, 233, 199, 245 |
| 171, 233, 199, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 171 x 233 x 199 x 49 = 7770181860
Therefore, the lowest common multiple of 855,466,796,980 is 7770181860.
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.
855 x 466 x 796 x 980 = 310807274400
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
466 : 1, 2, 233, 466
796 : 1, 2, 4, 199, 398, 796
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,466,796,980, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
466:2x 233
796:2x 2x 199
980:2x 2x 5x 7x 7
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 5 = 40
Therefore, the value for common factors is 40.
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 = 310807274400/(1x40)
LCM = 310807274400/40
LCM = 7770181860
Thus, we can understand that the LCM of 855,466,796,980 is 7770181860.
