Given numbers are 721,793,224,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,793,224,812 is 530586784.
Find LCM of 721,793,224,812 with Prime Factorization
| 2 | 721, 793, 224, 812 |
| 2 | 721, 793, 112, 406 |
| 7 | 721, 793, 56, 203 |
| 103, 793, 8, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 103 x 793 x 8 x 29 = 530586784
Therefore, the lowest common multiple of 721,793,224,812 is 530586784.
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.
721 x 793 x 224 x 812 = 103995009664
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.
721 : 1, 7, 103, 721
793 : 1, 13, 61, 793
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,793,224,812, is 1.
Now, the common factors can be found like this.
721:7x 103
793:13x 61
224:2x 2x 2x 2x 2x 7
812:2x 2x 7x 29
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 103995009664/(1x196)
LCM = 103995009664/196
LCM = 530586784
Thus, we can understand that the LCM of 721,793,224,812 is 530586784.
