Given numbers are 977,944,220,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,944,220,899 is 45602530160.
Find LCM of 977,944,220,899 with Prime Factorization
| 2 | 977, 944, 220, 899 |
| 2 | 977, 472, 110, 899 |
| 977, 236, 55, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 977 x 236 x 55 x 899 = 45602530160
Therefore, the lowest common multiple of 977,944,220,899 is 45602530160.
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 944 x 220 x 899 = 182410120640
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
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,944,220,899, is 1.
Now, the common factors can be found like this.
977:977
944:2x 2x 2x 2x 59
220:2x 2x 5x 11
899:29x 31
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 = 182410120640/(1x4)
LCM = 182410120640/4
LCM = 45602530160
Thus, we can understand that the LCM of 977,944,220,899 is 45602530160.
