Given numbers are 690,989,242,185,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,989,242,185,892 is 59243335140.
Find LCM of 690,989,242,185,892 with Prime Factorization
| 2 | 690, 989, 242, 185, 892 |
| 5 | 345, 989, 121, 185, 446 |
| 23 | 69, 989, 121, 37, 446 |
| 3, 43, 121, 37, 446 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 3 x 43 x 121 x 37 x 446 = 59243335140
Therefore, the lowest common multiple of 690,989,242,185,892 is 59243335140.
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.
690 x 989 x 242 x 185 x 892 = 27251934164400
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
989 : 1, 23, 43, 989
242 : 1, 2, 11, 22, 121, 242
185 : 1, 5, 37, 185
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,989,242,185,892, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
989:23x 43
242:2x 11x 11
185:5x 37
892:2x 2x 223
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 = 27251934164400/(1x460)
LCM = 27251934164400/460
LCM = 59243335140
Thus, we can understand that the LCM of 690,989,242,185,892 is 59243335140.
