Find LCM of 551,861,697,119,406 with Prime Factorization
| 7 | 551, 861, 697, 119, 406 |
| 17 | 551, 123, 697, 17, 58 |
| 29 | 551, 123, 41, 1, 58 |
| 41 | 19, 123, 41, 1, 2 |
| 19, 3, 1, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 29 x 41 x 19 x 3 x 1 x 1 x 2 = 16129974
Therefore, the lowest common multiple of 551,861,697,119,406 is 16129974.
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.
551 x 861 x 697 x 119 x 406 = 15975723058638
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.
551 : 1, 19, 29, 551
861 : 1, 3, 7, 21, 41, 123, 287, 861
697 : 1, 17, 41, 697
119 : 1, 7, 17, 119
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,861,697,119,406, is 1.
Now, the common factors can be found like this.
551:19x 29
861:3x 7x 41
697:17x 41
119:7x 17
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 17x 29x 41 = 990437
Therefore, the value for common factors is 990437.
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 = 15975723058638/(1x990437)
LCM = 15975723058638/990437
LCM = 16129974
Thus, we can understand that the LCM of 551,861,697,119,406 is 16129974.
