Given numbers are 501,945,420,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 501,945,420,220 is 6943860.
Find LCM of 501,945,420,220 with Prime Factorization
| 2 | 501, 945, 420, 220 |
| 2 | 501, 945, 210, 110 |
| 3 | 501, 945, 105, 55 |
| 5 | 167, 315, 35, 55 |
| 7 | 167, 63, 7, 11 |
| 167, 9, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 167 x 9 x 1 x 11 = 6943860
Therefore, the lowest common multiple of 501,945,420,220 is 6943860.
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.
501 x 945 x 420 x 220 = 43746318000
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.
501 : 1, 3, 167, 501
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
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
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,945,420,220, is 1.
Now, the common factors can be found like this.
501:3x 167
945:3x 3x 3x 5x 7
420:2x 2x 3x 5x 7
220:2x 2x 5x 11
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 3x 3x 5x 5x 7 = 6300
Therefore, the value for common factors is 6300.
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 = 43746318000/(1x6300)
LCM = 43746318000/6300
LCM = 6943860
Thus, we can understand that the LCM of 501,945,420,220 is 6943860.
