Given numbers are 842,209,628,741,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,209,628,741,220 is 10775132940.
Find LCM of 842,209,628,741,220 with Prime Factorization
| 2 | 842, 209, 628, 741, 220 |
| 2 | 421, 209, 314, 741, 110 |
| 11 | 421, 209, 157, 741, 55 |
| 19 | 421, 19, 157, 741, 5 |
| 421, 1, 157, 39, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 421 x 1 x 157 x 39 x 5 = 10775132940
Therefore, the lowest common multiple of 842,209,628,741,220 is 10775132940.
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.
842 x 209 x 628 x 741 x 220 = 18016022275680
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.
842 : 1, 2, 421, 842
209 : 1, 11, 19, 209
628 : 1, 2, 4, 157, 314, 628
741 : 1, 3, 13, 19, 39, 57, 247, 741
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 842,209,628,741,220, is 1.
Now, the common factors can be found like this.
842:2x 421
209:11x 19
628:2x 2x 157
741:3x 13x 19
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 2x 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 18016022275680/(1x1672)
LCM = 18016022275680/1672
LCM = 10775132940
Thus, we can understand that the LCM of 842,209,628,741,220 is 10775132940.
