The LCM of 721,442,546,616 is 42066024.
Find LCM of 721,442,546,616 with Prime Factorization
| 2 | 721, 442, 546, 616 |
| 7 | 721, 221, 273, 308 |
| 13 | 103, 221, 39, 44 |
| 103, 17, 3, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 103 x 17 x 3 x 44 = 42066024
Therefore, the lowest common multiple of 721,442,546,616 is 42066024.
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 442 x 546 x 616 = 107184229152
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,442,546,616, is 1.
Now, the common factors can be found like this.
721:7x 103
442:2x 13x 17
546:2x 3x 7x 13
616:2x 2x 2x 7x 11
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 7x 7x 13 = 2548
Therefore, the value for common factors is 2548.
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 = 107184229152/(1x2548)
LCM = 107184229152/2548
LCM = 42066024
Thus, we can understand that the LCM of 721,442,546,616 is 42066024.
