Given numbers are 220,785,836,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,785,836,321 is 210659460.
Find LCM of 220,785,836,321 with Prime Factorization
| 2 | 220, 785, 836, 321 |
| 2 | 110, 785, 418, 321 |
| 5 | 55, 785, 209, 321 |
| 11 | 11, 157, 209, 321 |
| 1, 157, 19, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 1 x 157 x 19 x 321 = 210659460
Therefore, the lowest common multiple of 220,785,836,321 is 210659460.
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 785 x 836 x 321 = 46345081200
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
785 : 1, 5, 157, 785
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,785,836,321, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
785:5x 157
836:2x 2x 11x 19
321:3x 107
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 = 46345081200/(1x220)
LCM = 46345081200/220
LCM = 210659460
Thus, we can understand that the LCM of 220,785,836,321 is 210659460.
