Given numbers are 655,410,805,974,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,410,805,974,910 is 54746119610.
Find LCM of 655,410,805,974,910 with Prime Factorization
| 2 | 655, 410, 805, 974, 910 |
| 5 | 655, 205, 805, 487, 455 |
| 7 | 131, 41, 161, 487, 91 |
| 131, 41, 23, 487, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 131 x 41 x 23 x 487 x 13 = 54746119610
Therefore, the lowest common multiple of 655,410,805,974,910 is 54746119610.
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.
655 x 410 x 805 x 974 x 910 = 191611418635000
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.
655 : 1, 5, 131, 655
410 : 1, 2, 5, 10, 41, 82, 205, 410
805 : 1, 5, 7, 23, 35, 115, 161, 805
974 : 1, 2, 487, 974
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,410,805,974,910, is 1.
Now, the common factors can be found like this.
655:5x 131
410:2x 5x 41
805:5x 7x 23
974:2x 487
910:2x 5x 7x 13
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 5x 5x 5x 7 = 3500
Therefore, the value for common factors is 3500.
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 = 191611418635000/(1x3500)
LCM = 191611418635000/3500
LCM = 54746119610
Thus, we can understand that the LCM of 655,410,805,974,910 is 54746119610.
