Given numbers are 721,578,595,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,578,595,777 is 231289590.
Find LCM of 721,578,595,777 with Prime Factorization
7 | 721, 578, 595, 777 |
17 | 103, 578, 85, 111 |
103, 34, 5, 111 |
Multiply the prime numbers at the bottom and the left side.
7 x 17 x 103 x 34 x 5 x 111 = 231289590
Therefore, the lowest common multiple of 721,578,595,777 is 231289590.
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 578 x 595 x 777 = 192664228470
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
578 : 1, 2, 17, 34, 289, 578
595 : 1, 5, 7, 17, 35, 85, 119, 595
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,578,595,777, is 1.
Now, the common factors can be found like this.
721:7x 103
578:2x 17x 17
595:5x 7x 17
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 17 = 833
Therefore, the value for common factors is 833.
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 = 192664228470/(1x833)
LCM = 192664228470/833
LCM = 231289590
Thus, we can understand that the LCM of 721,578,595,777 is 231289590.
