Given numbers are 781,412,760,687,564
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,412,760,687,564 is 1974042260520.
Find LCM of 781,412,760,687,564 with Prime Factorization
| 2 | 781, 412, 760, 687, 564 |
| 2 | 781, 206, 380, 687, 282 |
| 3 | 781, 103, 190, 687, 141 |
| 781, 103, 190, 229, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 781 x 103 x 190 x 229 x 47 = 1974042260520
Therefore, the lowest common multiple of 781,412,760,687,564 is 1974042260520.
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 412 x 760 x 687 x 564 = 94754028504960
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
412 : 1, 2, 4, 103, 206, 412
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
687 : 1, 3, 229, 687
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,412,760,687,564, is 1.
Now, the common factors can be found like this.
781:11x 71
412:2x 2x 103
760:2x 2x 2x 5x 19
687:3x 229
564:2x 2x 3x 47
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 3 = 48
Therefore, the value for common factors is 48.
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 = 94754028504960/(1x48)
LCM = 94754028504960/48
LCM = 1974042260520
Thus, we can understand that the LCM of 781,412,760,687,564 is 1974042260520.
