Given numbers are 513,649,104,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,649,104,420 is 1211890680.
Find LCM of 513,649,104,420 with Prime Factorization
| 2 | 513, 649, 104, 420 |
| 2 | 513, 649, 52, 210 |
| 3 | 513, 649, 26, 105 |
| 171, 649, 26, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 171 x 649 x 26 x 35 = 1211890680
Therefore, the lowest common multiple of 513,649,104,420 is 1211890680.
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.
513 x 649 x 104 x 420 = 14542688160
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
649 : 1, 11, 59, 649
104 : 1, 2, 4, 8, 13, 26, 52, 104
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,649,104,420, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
649:11x 59
104:2x 2x 2x 13
420:2x 2x 3x 5x 7
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 = 14542688160/(1x12)
LCM = 14542688160/12
LCM = 1211890680
Thus, we can understand that the LCM of 513,649,104,420 is 1211890680.
