Given numbers are 786,436,580,630
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,436,580,630 is 521754660.
Find LCM of 786,436,580,630 with Prime Factorization
| 2 | 786, 436, 580, 630 |
| 2 | 393, 218, 290, 315 |
| 3 | 393, 109, 145, 315 |
| 5 | 131, 109, 145, 105 |
| 131, 109, 29, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 131 x 109 x 29 x 21 = 521754660
Therefore, the lowest common multiple of 786,436,580,630 is 521754660.
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.
786 x 436 x 580 x 630 = 125221118400
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
436 : 1, 2, 4, 109, 218, 436
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,436,580,630, is 2.
Now, the common factors can be found like this.
786:2x 3x 131
436:2x 2x 109
580:2x 2x 5x 29
630:2x 3x 3x 5x 7
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 125221118400/(2x120)
LCM = 125221118400/240
LCM = 521754660
Thus, we can understand that the LCM of 786,436,580,630 is 521754660.
