Given numbers are 453,465,156,855,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,465,156,855,721 is 150052544460.
Find LCM of 453,465,156,855,721 with Prime Factorization
| 3 | 453, 465, 156, 855, 721 |
| 5 | 151, 155, 52, 285, 721 |
| 151, 31, 52, 57, 721 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 151 x 31 x 52 x 57 x 721 = 150052544460
Therefore, the lowest common multiple of 453,465,156,855,721 is 150052544460.
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.
453 x 465 x 156 x 855 x 721 = 20257093502100
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.
453 : 1, 3, 151, 453
465 : 1, 3, 5, 15, 31, 93, 155, 465
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,465,156,855,721, is 1.
Now, the common factors can be found like this.
453:3x 151
465:3x 5x 31
156:2x 2x 3x 13
855:3x 3x 5x 19
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 20257093502100/(1x135)
LCM = 20257093502100/135
LCM = 150052544460
Thus, we can understand that the LCM of 453,465,156,855,721 is 150052544460.
