Given numbers are 961,616,254,446,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 961,616,254,446,121 is 184418875256.
Find LCM of 961,616,254,446,121 with Prime Factorization
| 2 | 961, 616, 254, 446, 121 |
| 11 | 961, 308, 127, 223, 121 |
| 961, 28, 127, 223, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 961 x 28 x 127 x 223 x 11 = 184418875256
Therefore, the lowest common multiple of 961,616,254,446,121 is 184418875256.
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.
961 x 616 x 254 x 446 x 121 = 8114430511264
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.
961 : 1, 31, 961
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
254 : 1, 2, 127, 254
446 : 1, 2, 223, 446
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,616,254,446,121, is 1.
Now, the common factors can be found like this.
961:31x 31
616:2x 2x 2x 7x 11
254:2x 127
446:2x 223
121:11x 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 11 = 44
Therefore, the value for common factors is 44.
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 = 8114430511264/(1x44)
LCM = 8114430511264/44
LCM = 184418875256
Thus, we can understand that the LCM of 961,616,254,446,121 is 184418875256.
