Given numbers are 546,101,720,975
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,101,720,975 is 33087600.
Find LCM of 546,101,720,975 with Prime Factorization
| 2 | 546, 101, 720, 975 |
| 3 | 273, 101, 360, 975 |
| 5 | 91, 101, 120, 325 |
| 13 | 91, 101, 24, 65 |
| 7, 101, 24, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 7 x 101 x 24 x 5 = 33087600
Therefore, the lowest common multiple of 546,101,720,975 is 33087600.
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.
546 x 101 x 720 x 975 = 38712492000
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
101 : 1, 101
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
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,101,720,975, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
101:101
720:2x 2x 2x 2x 3x 3x 5
975:3x 5x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 13 = 1170
Therefore, the value for common factors is 1170.
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 = 38712492000/(1x1170)
LCM = 38712492000/1170
LCM = 33087600
Thus, we can understand that the LCM of 546,101,720,975 is 33087600.
