Given numbers are 705,725,611,621,370
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,725,611,621,370 is 20356473150.
Find LCM of 705,725,611,621,370 with Prime Factorization
| 3 | 705, 725, 611, 621, 370 |
| 5 | 235, 725, 611, 207, 370 |
| 47 | 47, 145, 611, 207, 74 |
| 1, 145, 13, 207, 74 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 47 x 1 x 145 x 13 x 207 x 74 = 20356473150
Therefore, the lowest common multiple of 705,725,611,621,370 is 20356473150.
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.
705 x 725 x 611 x 621 x 370 = 71756567853750
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
725 : 1, 5, 25, 29, 145, 725
611 : 1, 13, 47, 611
621 : 1, 3, 9, 23, 27, 69, 207, 621
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,725,611,621,370, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
725:5x 5x 29
611:13x 47
621:3x 3x 3x 23
370:2x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 47 = 3525
Therefore, the value for common factors is 3525.
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 = 71756567853750/(1x3525)
LCM = 71756567853750/3525
LCM = 20356473150
Thus, we can understand that the LCM of 705,725,611,621,370 is 20356473150.
