Find LCM of 728,700,663,971,493 with Prime Factorization
| 2 | 728, 700, 663, 971, 493 |
| 2 | 364, 350, 663, 971, 493 |
| 7 | 182, 175, 663, 971, 493 |
| 13 | 26, 25, 663, 971, 493 |
| 17 | 2, 25, 51, 971, 493 |
| 2, 25, 3, 971, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 17 x 2 x 25 x 3 x 971 x 29 = 26137183800
Therefore, the lowest common multiple of 728,700,663,971,493 is 26137183800.
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.
728 x 700 x 663 x 971 x 493 = 161736893354400
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
663 : 1, 3, 13, 17, 39, 51, 221, 663
971 : 1, 971
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,700,663,971,493, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
700:2x 2x 5x 5x 7
663:3x 13x 17
971:971
493:17x 29
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 13x 17 = 6188
Therefore, the value for common factors is 6188.
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 = 161736893354400/(1x6188)
LCM = 161736893354400/6188
LCM = 26137183800
Thus, we can understand that the LCM of 728,700,663,971,493 is 26137183800.
