Given numbers are 220,587,440,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,587,440,401 is 103570280.
Find LCM of 220,587,440,401 with Prime Factorization
| 2 | 220, 587, 440, 401 |
| 2 | 110, 587, 220, 401 |
| 5 | 55, 587, 110, 401 |
| 11 | 11, 587, 22, 401 |
| 1, 587, 2, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 1 x 587 x 2 x 401 = 103570280
Therefore, the lowest common multiple of 220,587,440,401 is 103570280.
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.
220 x 587 x 440 x 401 = 22785461600
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
587 : 1, 587
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,587,440,401, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
587:587
440:2x 2x 2x 5x 11
401:401
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 11 = 220
Therefore, the value for common factors is 220.
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 = 22785461600/(1x220)
LCM = 22785461600/220
LCM = 103570280
Thus, we can understand that the LCM of 220,587,440,401 is 103570280.
