Given numbers are 815,551,690,100,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,551,690,100,476 is 73745454300.
Find LCM of 815,551,690,100,476 with Prime Factorization
2 | 815, 551, 690, 100, 476 |
2 | 815, 551, 345, 50, 238 |
5 | 815, 551, 345, 25, 119 |
163, 551, 69, 5, 119 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 163 x 551 x 69 x 5 x 119 = 73745454300
Therefore, the lowest common multiple of 815,551,690,100,476 is 73745454300.
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.
815 x 551 x 690 x 100 x 476 = 14749090860000
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.
815 : 1, 5, 163, 815
551 : 1, 19, 29, 551
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,551,690,100,476, is 1.
Now, the common factors can be found like this.
815:5x 163
551:19x 29
690:2x 3x 5x 23
100:2x 2x 5x 5
476:2x 2x 7x 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 2x 2x 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 14749090860000/(1x200)
LCM = 14749090860000/200
LCM = 73745454300
Thus, we can understand that the LCM of 815,551,690,100,476 is 73745454300.
