Given numbers are 781,529,715,639,714
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,529,715,639,714 is 57522735270.
Find LCM of 781,529,715,639,714 with Prime Factorization
| 3 | 781, 529, 715, 639, 714 |
| 11 | 781, 529, 715, 213, 238 |
| 71 | 71, 529, 65, 213, 238 |
| 1, 529, 65, 3, 238 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 71 x 1 x 529 x 65 x 3 x 238 = 57522735270
Therefore, the lowest common multiple of 781,529,715,639,714 is 57522735270.
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 529 x 715 x 639 x 714 = 134775768737610
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
529 : 1, 23, 529
715 : 1, 5, 11, 13, 55, 65, 143, 715
639 : 1, 3, 9, 71, 213, 639
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,529,715,639,714, is 1.
Now, the common factors can be found like this.
781:11x 71
529:23x 23
715:5x 11x 13
639:3x 3x 71
714:2x 3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 71 = 2343
Therefore, the value for common factors is 2343.
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 = 134775768737610/(1x2343)
LCM = 134775768737610/2343
LCM = 57522735270
Thus, we can understand that the LCM of 781,529,715,639,714 is 57522735270.
