Given numbers are 732,989,666,912,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 732,989,666,912,438 is 445827448944.
Find LCM of 732,989,666,912,438 with Prime Factorization
| 2 | 732, 989, 666, 912, 438 |
| 2 | 366, 989, 333, 456, 219 |
| 3 | 183, 989, 333, 228, 219 |
| 61, 989, 111, 76, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 61 x 989 x 111 x 76 x 73 = 445827448944
Therefore, the lowest common multiple of 732,989,666,912,438 is 445827448944.
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.
732 x 989 x 666 x 912 x 438 = 192597457943808
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.
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
989 : 1, 23, 43, 989
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 732,989,666,912,438, is 1.
Now, the common factors can be found like this.
732:2x 2x 3x 61
989:23x 43
666:2x 3x 3x 37
912:2x 2x 2x 2x 3x 19
438:2x 3x 73
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 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 192597457943808/(1x432)
LCM = 192597457943808/432
LCM = 445827448944
Thus, we can understand that the LCM of 732,989,666,912,438 is 445827448944.
