Given numbers are 221,859,740,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,859,740,629 is 140480860.
Find LCM of 221,859,740,629 with Prime Factorization
| 17 | 221, 859, 740, 629 |
| 37 | 13, 859, 740, 37 |
| 13, 859, 20, 1 |
Multiply the prime numbers at the bottom and the left side.
17 x 37 x 13 x 859 x 20 x 1 = 140480860
Therefore, the lowest common multiple of 221,859,740,629 is 140480860.
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.
221 x 859 x 740 x 629 = 88362460940
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.
221 : 1, 13, 17, 221
859 : 1, 859
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,859,740,629, is 1.
Now, the common factors can be found like this.
221:13x 17
859:859
740:2x 2x 5x 37
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 37 = 629
Therefore, the value for common factors is 629.
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 = 88362460940/(1x629)
LCM = 88362460940/629
LCM = 140480860
Thus, we can understand that the LCM of 221,859,740,629 is 140480860.
