Given numbers are 670,460,798,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,460,798,931 is 86080260.
Find LCM of 670,460,798,931 with Prime Factorization
| 2 | 670, 460, 798, 931 |
| 5 | 335, 230, 399, 931 |
| 7 | 67, 46, 399, 931 |
| 19 | 67, 46, 57, 133 |
| 67, 46, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 19 x 67 x 46 x 3 x 7 = 86080260
Therefore, the lowest common multiple of 670,460,798,931 is 86080260.
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.
670 x 460 x 798 x 931 = 228973491600
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,460,798,931, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
460:2x 2x 5x 23
798:2x 3x 7x 19
931:7x 7x 19
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 7x 19 = 2660
Therefore, the value for common factors is 2660.
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 = 228973491600/(1x2660)
LCM = 228973491600/2660
LCM = 86080260
Thus, we can understand that the LCM of 670,460,798,931 is 86080260.
