The LCM of 784,898,672,611 is 1290490656.
Find LCM of 784,898,672,611 with Prime Factorization
| 2 | 784, 898, 672, 611 |
| 2 | 392, 449, 336, 611 |
| 2 | 196, 449, 168, 611 |
| 2 | 98, 449, 84, 611 |
| 7 | 49, 449, 42, 611 |
| 7, 449, 6, 611 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 7 x 449 x 6 x 611 = 1290490656
Therefore, the lowest common multiple of 784,898,672,611 is 1290490656.
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 898 x 672 x 611 = 289069906944
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
898 : 1, 2, 449, 898
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,898,672,611, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
898:2x 449
672:2x 2x 2x 2x 2x 3x 7
611:13x 47
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 7 = 224
Therefore, the value for common factors is 224.
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 = 289069906944/(1x224)
LCM = 289069906944/224
LCM = 1290490656
Thus, we can understand that the LCM of 784,898,672,611 is 1290490656.
