Given numbers are 906,972,328,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,972,328,780 is 782294760.
Find LCM of 906,972,328,780 with Prime Factorization
| 2 | 906, 972, 328, 780 |
| 2 | 453, 486, 164, 390 |
| 3 | 453, 243, 82, 195 |
| 151, 81, 82, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 151 x 81 x 82 x 65 = 782294760
Therefore, the lowest common multiple of 906,972,328,780 is 782294760.
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.
906 x 972 x 328 x 780 = 225300890880
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
328 : 1, 2, 4, 8, 41, 82, 164, 328
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,972,328,780, is 2.
Now, the common factors can be found like this.
906:2x 3x 151
972:2x 2x 3x 3x 3x 3x 3
328:2x 2x 2x 41
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 2x 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 225300890880/(2x144)
LCM = 225300890880/288
LCM = 782294760
Thus, we can understand that the LCM of 906,972,328,780 is 782294760.
