Given numbers are 560,690,989,795
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 560,690,989,795 is 88060560.
Find LCM of 560,690,989,795 with Prime Factorization
| 2 | 560, 690, 989, 795 |
| 3 | 280, 345, 989, 795 |
| 5 | 280, 115, 989, 265 |
| 23 | 56, 23, 989, 53 |
| 56, 1, 43, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 56 x 1 x 43 x 53 = 88060560
Therefore, the lowest common multiple of 560,690,989,795 is 88060560.
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.
560 x 690 x 989 x 795 = 303808932000
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
989 : 1, 23, 43, 989
795 : 1, 3, 5, 15, 53, 159, 265, 795
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,690,989,795, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
690:2x 3x 5x 23
989:23x 43
795:3x 5x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 23 = 3450
Therefore, the value for common factors is 3450.
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 = 303808932000/(1x3450)
LCM = 303808932000/3450
LCM = 88060560
Thus, we can understand that the LCM of 560,690,989,795 is 88060560.
