Find LCM of 282,728,731,757,663 with Prime Factorization
2 | 282, 728, 731, 757, 663 |
3 | 141, 364, 731, 757, 663 |
13 | 47, 364, 731, 757, 221 |
17 | 47, 28, 731, 757, 17 |
47, 28, 43, 757, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 47 x 28 x 43 x 757 x 1 = 56802015816
Therefore, the lowest common multiple of 282,728,731,757,663 is 56802015816.
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.
282 x 728 x 731 x 757 x 663 = 75319472972016
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
731 : 1, 17, 43, 731
757 : 1, 757
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,728,731,757,663, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
728:2x 2x 2x 7x 13
731:17x 43
757:757
663:3x 13x 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 3x 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 75319472972016/(1x1326)
LCM = 75319472972016/1326
LCM = 56802015816
Thus, we can understand that the LCM of 282,728,731,757,663 is 56802015816.
