Given numbers are 781,260,800,210,716
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,260,800,210,716 is 30532101600.
Find LCM of 781,260,800,210,716 with Prime Factorization
| 2 | 781, 260, 800, 210, 716 |
| 2 | 781, 130, 400, 105, 358 |
| 5 | 781, 65, 200, 105, 179 |
| 781, 13, 40, 21, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 781 x 13 x 40 x 21 x 179 = 30532101600
Therefore, the lowest common multiple of 781,260,800,210,716 is 30532101600.
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.
781 x 260 x 800 x 210 x 716 = 24425681280000
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.
781 : 1, 11, 71, 781
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,260,800,210,716, is 1.
Now, the common factors can be found like this.
781:11x 71
260:2x 2x 5x 13
800:2x 2x 2x 2x 2x 5x 5
210:2x 3x 5x 7
716:2x 2x 179
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 2x 5x 5 = 800
Therefore, the value for common factors is 800.
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 = 24425681280000/(1x800)
LCM = 24425681280000/800
LCM = 30532101600
Thus, we can understand that the LCM of 781,260,800,210,716 is 30532101600.
