Given numbers are 751,568,374,805,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 751,568,374,805,690 is 192640241640.
Find LCM of 751,568,374,805,690 with Prime Factorization
| 2 | 751, 568, 374, 805, 690 |
| 5 | 751, 284, 187, 805, 345 |
| 23 | 751, 284, 187, 161, 69 |
| 751, 284, 187, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 751 x 284 x 187 x 7 x 3 = 192640241640
Therefore, the lowest common multiple of 751,568,374,805,690 is 192640241640.
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.
751 x 568 x 374 x 805 x 690 = 88614511154400
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.
751 : 1, 751
568 : 1, 2, 4, 8, 71, 142, 284, 568
374 : 1, 2, 11, 17, 22, 34, 187, 374
805 : 1, 5, 7, 23, 35, 115, 161, 805
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,568,374,805,690, is 1.
Now, the common factors can be found like this.
751:751
568:2x 2x 2x 71
374:2x 11x 17
805:5x 7x 23
690:2x 3x 5x 23
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 23 = 460
Therefore, the value for common factors is 460.
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 = 88614511154400/(1x460)
LCM = 88614511154400/460
LCM = 192640241640
Thus, we can understand that the LCM of 751,568,374,805,690 is 192640241640.
