Given numbers are 357,838,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 357,838,220 is 32908260.
Find LCM of 357,838,220 with Prime Factorization
| 2 | 357, 838, 220 |
| 357, 419, 110 |
Multiply the prime numbers at the bottom and the left side.
2 x 357 x 419 x 110 = 32908260
Therefore, the lowest common multiple of 357,838,220 is 32908260.
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.
357 x 838 x 220 = 65816520
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.
357 : 1, 3, 7, 17, 21, 51, 119, 357
838 : 1, 2, 419, 838
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 357,838,220, is 1.
Now, the common factors can be found like this.
357:3x 7x 17
838:2x 419
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.
2 = 2
Therefore, the value for common factors is 2.
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 = 65816520/(1x2)
LCM = 65816520/2
LCM = 32908260
Thus, we can understand that the LCM of 357,838,220 is 32908260.
