Given numbers are 153,943,436,221,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,943,436,221,646 is 15537694068.
Find LCM of 153,943,436,221,646 with Prime Factorization
| 2 | 153, 943, 436, 221, 646 |
| 17 | 153, 943, 218, 221, 323 |
| 9, 943, 218, 13, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 9 x 943 x 218 x 13 x 19 = 15537694068
Therefore, the lowest common multiple of 153,943,436,221,646 is 15537694068.
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.
153 x 943 x 436 x 221 x 646 = 8980787171304
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.
153 : 1, 3, 9, 17, 51, 153
943 : 1, 23, 41, 943
436 : 1, 2, 4, 109, 218, 436
221 : 1, 13, 17, 221
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,943,436,221,646, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
943:23x 41
436:2x 2x 109
221:13x 17
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17 = 578
Therefore, the value for common factors is 578.
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 = 8980787171304/(1x578)
LCM = 8980787171304/578
LCM = 15537694068
Thus, we can understand that the LCM of 153,943,436,221,646 is 15537694068.
