Find LCM of 855,985,819,697,902 with Prime Factorization
| 3 | 855, 985, 819, 697, 902 |
| 3 | 285, 985, 273, 697, 902 |
| 5 | 95, 985, 91, 697, 902 |
| 41 | 19, 197, 91, 697, 902 |
| 19, 197, 91, 17, 22 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 41 x 19 x 197 x 91 x 17 x 22 = 235033188390
Therefore, the lowest common multiple of 855,985,819,697,902 is 235033188390.
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 985 x 819 x 697 x 902 = 433636232579550
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
985 : 1, 5, 197, 985
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
697 : 1, 17, 41, 697
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,985,819,697,902, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
985:5x 197
819:3x 3x 7x 13
697:17x 41
902:2x 11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 41 = 1845
Therefore, the value for common factors is 1845.
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 = 433636232579550/(1x1845)
LCM = 433636232579550/1845
LCM = 235033188390
Thus, we can understand that the LCM of 855,985,819,697,902 is 235033188390.
