Given numbers are 946,793,505,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,793,505,780 is 2273039340.
Find LCM of 946,793,505,780 with Prime Factorization
| 2 | 946, 793, 505, 780 |
| 5 | 473, 793, 505, 390 |
| 13 | 473, 793, 101, 78 |
| 473, 61, 101, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 473 x 61 x 101 x 6 = 2273039340
Therefore, the lowest common multiple of 946,793,505,780 is 2273039340.
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.
946 x 793 x 505 x 780 = 295495114200
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
793 : 1, 13, 61, 793
505 : 1, 5, 101, 505
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,793,505,780, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
793:13x 61
505:5x 101
780:2x 2x 3x 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 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 295495114200/(1x130)
LCM = 295495114200/130
LCM = 2273039340
Thus, we can understand that the LCM of 946,793,505,780 is 2273039340.
