Given numbers are 292,580,780,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 292,580,780,890 is 146962140.
Find LCM of 292,580,780,890 with Prime Factorization
| 2 | 292, 580, 780, 890 |
| 2 | 146, 290, 390, 445 |
| 5 | 73, 145, 195, 445 |
| 73, 29, 39, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 73 x 29 x 39 x 89 = 146962140
Therefore, the lowest common multiple of 292,580,780,890 is 146962140.
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.
292 x 580 x 780 x 890 = 117569712000
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.
292 : 1, 2, 4, 73, 146, 292
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
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
890 : 1, 2, 5, 10, 89, 178, 445, 890
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 292,580,780,890, is 2.
Now, the common factors can be found like this.
292:2x 2x 73
580:2x 2x 5x 29
780:2x 2x 3x 5x 13
890:2x 5x 89
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 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 117569712000/(2x400)
LCM = 117569712000/800
LCM = 146962140
Thus, we can understand that the LCM of 292,580,780,890 is 146962140.
