Given numbers are 326,780,646,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 326,780,646,247 is 41066220.
Find LCM of 326,780,646,247 with Prime Factorization
2 | 326, 780, 646, 247 |
13 | 163, 390, 323, 247 |
19 | 163, 30, 323, 19 |
163, 30, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 163 x 30 x 17 x 1 = 41066220
Therefore, the lowest common multiple of 326,780,646,247 is 41066220.
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.
326 x 780 x 646 x 247 = 40573425360
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.
326 : 1, 2, 163, 326
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
646 : 1, 2, 17, 19, 34, 38, 323, 646
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,780,646,247, is 1.
Now, the common factors can be found like this.
326:2x 163
780:2x 2x 3x 5x 13
646:2x 17x 19
247:13x 19
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 13x 19 = 988
Therefore, the value for common factors is 988.
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 = 40573425360/(1x988)
LCM = 40573425360/988
LCM = 41066220
Thus, we can understand that the LCM of 326,780,646,247 is 41066220.
