Given numbers are 551,505,781,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,505,781,680 is 29555133080.
Find LCM of 551,505,781,680 with Prime Factorization
| 5 | 551, 505, 781, 680 |
| 551, 101, 781, 136 |
Multiply the prime numbers at the bottom and the left side.
5 x 551 x 101 x 781 x 136 = 29555133080
Therefore, the lowest common multiple of 551,505,781,680 is 29555133080.
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 505 x 781 x 680 = 147775665400
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
505 : 1, 5, 101, 505
781 : 1, 11, 71, 781
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,505,781,680, is 1.
Now, the common factors can be found like this.
551:19x 29
505:5x 101
781:11x 71
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 147775665400/(1x5)
LCM = 147775665400/5
LCM = 29555133080
Thus, we can understand that the LCM of 551,505,781,680 is 29555133080.
