Given numbers are 721,540,275,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,540,275,475 is 406860300.
Find LCM of 721,540,275,475 with Prime Factorization
| 5 | 721, 540, 275, 475 |
| 5 | 721, 108, 55, 95 |
| 721, 108, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 721 x 108 x 11 x 19 = 406860300
Therefore, the lowest common multiple of 721,540,275,475 is 406860300.
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.
721 x 540 x 275 x 475 = 50857537500
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.
721 : 1, 7, 103, 721
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
275 : 1, 5, 11, 25, 55, 275
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,540,275,475, is 1.
Now, the common factors can be found like this.
721:7x 103
540:2x 2x 3x 3x 3x 5
275:5x 5x 11
475:5x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5 = 125
Therefore, the value for common factors is 125.
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 = 50857537500/(1x125)
LCM = 50857537500/125
LCM = 406860300
Thus, we can understand that the LCM of 721,540,275,475 is 406860300.
