Given numbers are 889,961,174,120,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,961,174,120,154 is 32703714120.
Find LCM of 889,961,174,120,154 with Prime Factorization
| 2 | 889, 961, 174, 120, 154 |
| 3 | 889, 961, 87, 60, 77 |
| 7 | 889, 961, 29, 20, 77 |
| 127, 961, 29, 20, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 127 x 961 x 29 x 20 x 11 = 32703714120
Therefore, the lowest common multiple of 889,961,174,120,154 is 32703714120.
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.
889 x 961 x 174 x 120 x 154 = 2747111986080
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.
889 : 1, 7, 127, 889
961 : 1, 31, 961
174 : 1, 2, 3, 6, 29, 58, 87, 174
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,961,174,120,154, is 1.
Now, the common factors can be found like this.
889:7x 127
961:31x 31
174:2x 3x 29
120:2x 2x 2x 3x 5
154:2x 7x 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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 2747111986080/(1x84)
LCM = 2747111986080/84
LCM = 32703714120
Thus, we can understand that the LCM of 889,961,174,120,154 is 32703714120.
