Given numbers are 773,390,914,992,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 773,390,914,992,639 is 14555314069920.
Find LCM of 773,390,914,992,639 with Prime Factorization
| 2 | 773, 390, 914, 992, 639 |
| 3 | 773, 195, 457, 496, 639 |
| 773, 65, 457, 496, 213 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 773 x 65 x 457 x 496 x 213 = 14555314069920
Therefore, the lowest common multiple of 773,390,914,992,639 is 14555314069920.
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.
773 x 390 x 914 x 992 x 639 = 174663768839040
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.
773 : 1, 773
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
914 : 1, 2, 457, 914
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,390,914,992,639, is 1.
Now, the common factors can be found like this.
773:773
390:2x 3x 5x 13
914:2x 457
992:2x 2x 2x 2x 2x 31
639:3x 3x 71
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 3 = 12
Therefore, the value for common factors is 12.
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 = 174663768839040/(1x12)
LCM = 174663768839040/12
LCM = 14555314069920
Thus, we can understand that the LCM of 773,390,914,992,639 is 14555314069920.
