Given numbers are 979,249,176,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,249,176,320 is 78006720.
Find LCM of 979,249,176,320 with Prime Factorization
2 | 979, 249, 176, 320 |
2 | 979, 249, 88, 160 |
2 | 979, 249, 44, 80 |
2 | 979, 249, 22, 40 |
11 | 979, 249, 11, 20 |
89, 249, 1, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 89 x 249 x 1 x 20 = 78006720
Therefore, the lowest common multiple of 979,249,176,320 is 78006720.
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.
979 x 249 x 176 x 320 = 13729182720
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.
979 : 1, 11, 89, 979
249 : 1, 3, 83, 249
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,249,176,320, is 1.
Now, the common factors can be found like this.
979:11x 89
249:3x 83
176:2x 2x 2x 2x 11
320:2x 2x 2x 2x 2x 2x 5
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 11 = 176
Therefore, the value for common factors is 176.
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 = 13729182720/(1x176)
LCM = 13729182720/176
LCM = 78006720
Thus, we can understand that the LCM of 979,249,176,320 is 78006720.
