Given numbers are 570,751,105,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,751,105,420 is 5992980.
Find LCM of 570,751,105,420 with Prime Factorization
| 2 | 570, 751, 105, 420 |
| 3 | 285, 751, 105, 210 |
| 5 | 95, 751, 35, 70 |
| 7 | 19, 751, 7, 14 |
| 19, 751, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 19 x 751 x 1 x 2 = 5992980
Therefore, the lowest common multiple of 570,751,105,420 is 5992980.
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.
570 x 751 x 105 x 420 = 18877887000
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
751 : 1, 751
105 : 1, 3, 5, 7, 15, 21, 35, 105
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 570,751,105,420, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
751:751
105:3x 5x 7
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 3x 3x 5x 5x 7 = 3150
Therefore, the value for common factors is 3150.
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 = 18877887000/(1x3150)
LCM = 18877887000/3150
LCM = 5992980
Thus, we can understand that the LCM of 570,751,105,420 is 5992980.
