Given numbers are 721,142,126,493,510
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,142,126,493,510 is 2271344670.
Find LCM of 721,142,126,493,510 with Prime Factorization
| 2 | 721, 142, 126, 493, 510 |
| 3 | 721, 71, 63, 493, 255 |
| 7 | 721, 71, 21, 493, 85 |
| 17 | 103, 71, 3, 493, 85 |
| 103, 71, 3, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 103 x 71 x 3 x 29 x 5 = 2271344670
Therefore, the lowest common multiple of 721,142,126,493,510 is 2271344670.
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 142 x 126 x 493 x 510 = 3243480188760
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
142 : 1, 2, 71, 142
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
493 : 1, 17, 29, 493
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,142,126,493,510, is 1.
Now, the common factors can be found like this.
721:7x 103
142:2x 71
126:2x 3x 3x 7
493:17x 29
510:2x 3x 5x 17
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 7x 17 = 1428
Therefore, the value for common factors is 1428.
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 = 3243480188760/(1x1428)
LCM = 3243480188760/1428
LCM = 2271344670
Thus, we can understand that the LCM of 721,142,126,493,510 is 2271344670.
