Given numbers are 430,628,820,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,628,820,986 is 2729159260.
Find LCM of 430,628,820,986 with Prime Factorization
| 2 | 430, 628, 820, 986 |
| 2 | 215, 314, 410, 493 |
| 5 | 215, 157, 205, 493 |
| 43, 157, 41, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 157 x 41 x 493 = 2729159260
Therefore, the lowest common multiple of 430,628,820,986 is 2729159260.
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.
430 x 628 x 820 x 986 = 218332740800
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
628 : 1, 2, 4, 157, 314, 628
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
986 : 1, 2, 17, 29, 34, 58, 493, 986
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,628,820,986, is 2.
Now, the common factors can be found like this.
430:2x 5x 43
628:2x 2x 157
820:2x 2x 5x 41
986:2x 17x 29
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 5 = 40
Therefore, the value for common factors is 40.
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 = 218332740800/(2x40)
LCM = 218332740800/80
LCM = 2729159260
Thus, we can understand that the LCM of 430,628,820,986 is 2729159260.
