Given numbers are 930,286,780,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 930,286,780,542 is 72080580.
Find LCM of 930,286,780,542 with Prime Factorization
| 2 | 930, 286, 780, 542 |
| 3 | 465, 143, 390, 271 |
| 5 | 155, 143, 130, 271 |
| 13 | 31, 143, 26, 271 |
| 31, 11, 2, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 31 x 11 x 2 x 271 = 72080580
Therefore, the lowest common multiple of 930,286,780,542 is 72080580.
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.
930 x 286 x 780 x 542 = 112445704800
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.
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
286 : 1, 2, 11, 13, 22, 26, 143, 286
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
542 : 1, 2, 271, 542
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,286,780,542, is 2.
Now, the common factors can be found like this.
930:2x 3x 5x 31
286:2x 11x 13
780:2x 2x 3x 5x 13
542:2x 271
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 112445704800/(2x780)
LCM = 112445704800/1560
LCM = 72080580
Thus, we can understand that the LCM of 930,286,780,542 is 72080580.
