Given numbers are 577,686,672,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 577,686,672,660 is 1044970080.
Find LCM of 577,686,672,660 with Prime Factorization
| 2 | 577, 686, 672, 660 |
| 2 | 577, 343, 336, 330 |
| 3 | 577, 343, 168, 165 |
| 7 | 577, 343, 56, 55 |
| 577, 49, 8, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 577 x 49 x 8 x 55 = 1044970080
Therefore, the lowest common multiple of 577,686,672,660 is 1044970080.
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.
577 x 686 x 672 x 660 = 175554973440
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.
577 : 1, 577
686 : 1, 2, 7, 14, 49, 98, 343, 686
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
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,686,672,660, is 1.
Now, the common factors can be found like this.
577:577
686:2x 7x 7x 7
672:2x 2x 2x 2x 2x 3x 7
660:2x 2x 3x 5x 11
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 175554973440/(1x168)
LCM = 175554973440/168
LCM = 1044970080
Thus, we can understand that the LCM of 577,686,672,660 is 1044970080.
