Find LCM of 640,353,977,309,800 with Prime Factorization
2 | 640, 353, 977, 309, 800 |
2 | 320, 353, 977, 309, 400 |
2 | 160, 353, 977, 309, 200 |
2 | 80, 353, 977, 309, 100 |
2 | 40, 353, 977, 309, 50 |
5 | 20, 353, 977, 309, 25 |
4, 353, 977, 309, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 4 x 353 x 977 x 309 x 5 = 341018332800
Therefore, the lowest common multiple of 640,353,977,309,800 is 341018332800.
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.
640 x 353 x 977 x 309 x 800 = 54562933248000
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
353 : 1, 353
977 : 1, 977
309 : 1, 3, 103, 309
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,353,977,309,800, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
353:353
977:977
309:3x 103
800:2x 2x 2x 2x 2x 5x 5
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 54562933248000/(1x160)
LCM = 54562933248000/160
LCM = 341018332800
Thus, we can understand that the LCM of 640,353,977,309,800 is 341018332800.
