Given numbers are 380,979,737,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,979,737,720 is 897312240.
Find LCM of 380,979,737,720 with Prime Factorization
| 2 | 380, 979, 737, 720 |
| 2 | 190, 979, 737, 360 |
| 5 | 95, 979, 737, 180 |
| 11 | 19, 979, 737, 36 |
| 19, 89, 67, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 19 x 89 x 67 x 36 = 897312240
Therefore, the lowest common multiple of 380,979,737,720 is 897312240.
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.
380 x 979 x 737 x 720 = 197408692800
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
979 : 1, 11, 89, 979
737 : 1, 11, 67, 737
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,979,737,720, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
979:11x 89
737:11x 67
720:2x 2x 2x 2x 3x 3x 5
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 197408692800/(1x220)
LCM = 197408692800/220
LCM = 897312240
Thus, we can understand that the LCM of 380,979,737,720 is 897312240.
