Given numbers are 779,646,646,224
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,646,646,224 is 2966432.
Find LCM of 779,646,646,224 with Prime Factorization
2 | 779, 646, 646, 224 |
17 | 779, 323, 323, 112 |
19 | 779, 19, 19, 112 |
41, 1, 1, 112 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 41 x 1 x 1 x 112 = 2966432
Therefore, the lowest common multiple of 779,646,646,224 is 2966432.
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.
779 x 646 x 646 x 224 = 72819972736
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.
779 : 1, 19, 41, 779
646 : 1, 2, 17, 19, 34, 38, 323, 646
646 : 1, 2, 17, 19, 34, 38, 323, 646
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,646,646,224, is 1.
Now, the common factors can be found like this.
779:19x 41
646:2x 17x 19
646:2x 17x 19
224:2x 2x 2x 2x 2x 7
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 17x 19x 19 = 24548
Therefore, the value for common factors is 24548.
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 = 72819972736/(1x24548)
LCM = 72819972736/24548
LCM = 2966432
Thus, we can understand that the LCM of 779,646,646,224 is 2966432.
