Given numbers are 672,909,488,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,909,488,618 is 1279319328.
Find LCM of 672,909,488,618 with Prime Factorization
| 2 | 672, 909, 488, 618 |
| 2 | 336, 909, 244, 309 |
| 2 | 168, 909, 122, 309 |
| 3 | 84, 909, 61, 309 |
| 28, 303, 61, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 28 x 303 x 61 x 103 = 1279319328
Therefore, the lowest common multiple of 672,909,488,618 is 1279319328.
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.
672 x 909 x 488 x 618 = 184221983232
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.
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
909 : 1, 3, 9, 101, 303, 909
488 : 1, 2, 4, 8, 61, 122, 244, 488
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,909,488,618, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
909:3x 3x 101
488:2x 2x 2x 61
618:2x 3x 103
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 184221983232/(1x144)
LCM = 184221983232/144
LCM = 1279319328
Thus, we can understand that the LCM of 672,909,488,618 is 1279319328.
