Given numbers are 302,650,786,721,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 302,650,786,721,405 is 750899617650.
Find LCM of 302,650,786,721,405 with Prime Factorization
| 2 | 302, 650, 786, 721, 405 |
| 3 | 151, 325, 393, 721, 405 |
| 5 | 151, 325, 131, 721, 135 |
| 151, 65, 131, 721, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 151 x 65 x 131 x 721 x 27 = 750899617650
Therefore, the lowest common multiple of 302,650,786,721,405 is 750899617650.
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.
302 x 650 x 786 x 721 x 405 = 45053977059000
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.
302 : 1, 2, 151, 302
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
786 : 1, 2, 3, 6, 131, 262, 393, 786
721 : 1, 7, 103, 721
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,650,786,721,405, is 1.
Now, the common factors can be found like this.
302:2x 151
650:2x 5x 5x 13
786:2x 3x 131
721:7x 103
405:3x 3x 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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 45053977059000/(1x60)
LCM = 45053977059000/60
LCM = 750899617650
Thus, we can understand that the LCM of 302,650,786,721,405 is 750899617650.
