Given numbers are 280,400,917,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,400,917,631 is 231450800.
Find LCM of 280,400,917,631 with Prime Factorization
2 | 280, 400, 917, 631 |
2 | 140, 200, 917, 631 |
2 | 70, 100, 917, 631 |
5 | 35, 50, 917, 631 |
7 | 7, 10, 917, 631 |
1, 10, 131, 631 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 1 x 10 x 131 x 631 = 231450800
Therefore, the lowest common multiple of 280,400,917,631 is 231450800.
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.
280 x 400 x 917 x 631 = 64806224000
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
917 : 1, 7, 131, 917
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,400,917,631, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
400:2x 2x 2x 2x 5x 5
917:7x 131
631:631
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 7 = 280
Therefore, the value for common factors is 280.
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 = 64806224000/(1x280)
LCM = 64806224000/280
LCM = 231450800
Thus, we can understand that the LCM of 280,400,917,631 is 231450800.
