Given numbers are 972,358,987,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,358,987,554 is 15856048404.
Find LCM of 972,358,987,554 with Prime Factorization
| 2 | 972, 358, 987, 554 |
| 3 | 486, 179, 987, 277 |
| 162, 179, 329, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 162 x 179 x 329 x 277 = 15856048404
Therefore, the lowest common multiple of 972,358,987,554 is 15856048404.
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.
972 x 358 x 987 x 554 = 190272580848
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
358 : 1, 2, 179, 358
987 : 1, 3, 7, 21, 47, 141, 329, 987
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,358,987,554, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
358:2x 179
987:3x 7x 47
554:2x 277
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 = 190272580848/(1x12)
LCM = 190272580848/12
LCM = 15856048404
Thus, we can understand that the LCM of 972,358,987,554 is 15856048404.
