The LCM of 416,780,755,554 is 261000480.
Find LCM of 416,780,755,554 with Prime Factorization
2 | 416, 780, 755, 554 |
2 | 208, 390, 755, 277 |
5 | 104, 195, 755, 277 |
13 | 104, 39, 151, 277 |
8, 3, 151, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 8 x 3 x 151 x 277 = 261000480
Therefore, the lowest common multiple of 416,780,755,554 is 261000480.
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.
416 x 780 x 755 x 554 = 135720249600
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.
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
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
755 : 1, 5, 151, 755
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,780,755,554, is 1.
Now, the common factors can be found like this.
416:2x 2x 2x 2x 2x 13
780:2x 2x 3x 5x 13
755:5x 151
554:2x 277
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 135720249600/(1x520)
LCM = 135720249600/520
LCM = 261000480
Thus, we can understand that the LCM of 416,780,755,554 is 261000480.
