The LCM of 780,156,748,481 is 5396820.
Find LCM of 780,156,748,481 with Prime Factorization
2 | 780, 156, 748, 481 |
2 | 390, 78, 374, 481 |
3 | 195, 39, 187, 481 |
13 | 65, 13, 187, 481 |
5, 1, 187, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 5 x 1 x 187 x 37 = 5396820
Therefore, the lowest common multiple of 780,156,748,481 is 5396820.
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.
780 x 156 x 748 x 481 = 43779003840
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.
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
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,156,748,481, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
156:2x 2x 3x 13
748:2x 2x 11x 17
481:13x 37
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 3x 13x 13 = 8112
Therefore, the value for common factors is 8112.
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 = 43779003840/(1x8112)
LCM = 43779003840/8112
LCM = 5396820
Thus, we can understand that the LCM of 780,156,748,481 is 5396820.
