Given numbers are 487,404,620,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,404,620,707 is 213471580.
Find LCM of 487,404,620,707 with Prime Factorization
| 2 | 487, 404, 620, 707 |
| 2 | 487, 202, 310, 707 |
| 101 | 487, 101, 155, 707 |
| 487, 1, 155, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 487 x 1 x 155 x 7 = 213471580
Therefore, the lowest common multiple of 487,404,620,707 is 213471580.
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.
487 x 404 x 620 x 707 = 86242518320
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.
487 : 1, 487
404 : 1, 2, 4, 101, 202, 404
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,404,620,707, is 1.
Now, the common factors can be found like this.
487:487
404:2x 2x 101
620:2x 2x 5x 31
707:7x 101
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 101 = 404
Therefore, the value for common factors is 404.
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 = 86242518320/(1x404)
LCM = 86242518320/404
LCM = 213471580
Thus, we can understand that the LCM of 487,404,620,707 is 213471580.
