Given numbers are 977,220,887,432
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,220,887,432 is 20590392240.
Find LCM of 977,220,887,432 with Prime Factorization
| 2 | 977, 220, 887, 432 |
| 2 | 977, 110, 887, 216 |
| 977, 55, 887, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 977 x 55 x 887 x 108 = 20590392240
Therefore, the lowest common multiple of 977,220,887,432 is 20590392240.
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.
977 x 220 x 887 x 432 = 82361568960
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.
977 : 1, 977
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
887 : 1, 887
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,220,887,432, is 1.
Now, the common factors can be found like this.
977:977
220:2x 2x 5x 11
887:887
432:2x 2x 2x 2x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 82361568960/(1x4)
LCM = 82361568960/4
LCM = 20590392240
Thus, we can understand that the LCM of 977,220,887,432 is 20590392240.
