Find LCM of 155,782,651,918 with Prime Factorization
| 2 | 155, 782, 651, 918 |
| 3 | 155, 391, 651, 459 |
| 17 | 155, 391, 217, 153 |
| 31 | 155, 23, 217, 9 |
| 5, 23, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 31 x 5 x 23 x 7 x 9 = 22908690
Therefore, the lowest common multiple of 155,782,651,918 is 22908690.
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.
155 x 782 x 651 x 918 = 72437277780
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.
155 : 1, 5, 31, 155
782 : 1, 2, 17, 23, 34, 46, 391, 782
651 : 1, 3, 7, 21, 31, 93, 217, 651
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,782,651,918, is 1.
Now, the common factors can be found like this.
155:5x 31
782:2x 17x 23
651:3x 7x 31
918:2x 3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17x 31 = 3162
Therefore, the value for common factors is 3162.
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 = 72437277780/(1x3162)
LCM = 72437277780/3162
LCM = 22908690
Thus, we can understand that the LCM of 155,782,651,918 is 22908690.
