The LCM of 784,201,490,633 is 166251120.
Find LCM of 784,201,490,633 with Prime Factorization
| 2 | 784, 201, 490, 633 |
| 3 | 392, 201, 245, 633 |
| 7 | 392, 67, 245, 211 |
| 7 | 56, 67, 35, 211 |
| 8, 67, 5, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 8 x 67 x 5 x 211 = 166251120
Therefore, the lowest common multiple of 784,201,490,633 is 166251120.
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.
784 x 201 x 490 x 633 = 48877829280
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
201 : 1, 3, 67, 201
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
633 : 1, 3, 211, 633
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,201,490,633, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
201:3x 67
490:2x 5x 7x 7
633:3x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 48877829280/(1x294)
LCM = 48877829280/294
LCM = 166251120
Thus, we can understand that the LCM of 784,201,490,633 is 166251120.
