Given numbers are 173,578,989,654,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 173,578,989,654,474 is 2554730406978.
Find LCM of 173,578,989,654,474 with Prime Factorization
| 2 | 173, 578, 989, 654, 474 |
| 3 | 173, 289, 989, 327, 237 |
| 173, 289, 989, 109, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 173 x 289 x 989 x 109 x 79 = 2554730406978
Therefore, the lowest common multiple of 173,578,989,654,474 is 2554730406978.
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.
173 x 578 x 989 x 654 x 474 = 30656764883736
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.
173 : 1, 173
578 : 1, 2, 17, 34, 289, 578
989 : 1, 23, 43, 989
654 : 1, 2, 3, 6, 109, 218, 327, 654
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,578,989,654,474, is 1.
Now, the common factors can be found like this.
173:173
578:2x 17x 17
989:23x 43
654:2x 3x 109
474:2x 3x 79
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 3 = 12
Therefore, the value for common factors is 12.
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 = 30656764883736/(1x12)
LCM = 30656764883736/12
LCM = 2554730406978
Thus, we can understand that the LCM of 173,578,989,654,474 is 2554730406978.
