Find LCM of 346,137,780,830,520 with Prime Factorization
2 | 346, 137, 780, 830, 520 |
2 | 173, 137, 390, 415, 260 |
5 | 173, 137, 195, 415, 130 |
13 | 173, 137, 39, 83, 26 |
173, 137, 3, 83, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 173 x 137 x 3 x 83 x 2 = 3068805480
Therefore, the lowest common multiple of 346,137,780,830,520 is 3068805480.
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.
346 x 137 x 780 x 830 x 520 = 15957788496000
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.
346 : 1, 2, 173, 346
137 : 1, 137
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
830 : 1, 2, 5, 10, 83, 166, 415, 830
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 346,137,780,830,520, is 1.
Now, the common factors can be found like this.
346:2x 173
137:137
780:2x 2x 3x 5x 13
830:2x 5x 83
520:2x 2x 2x 5x 13
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 5x 5x 13 = 5200
Therefore, the value for common factors is 5200.
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 = 15957788496000/(1x5200)
LCM = 15957788496000/5200
LCM = 3068805480
Thus, we can understand that the LCM of 346,137,780,830,520 is 3068805480.
