Find LCM of 772,393,621,812,423 with Prime Factorization
| 2 | 772, 393, 621, 812, 423 |
| 2 | 386, 393, 621, 406, 423 |
| 3 | 193, 393, 621, 203, 423 |
| 3 | 193, 131, 207, 203, 141 |
| 193, 131, 69, 203, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 193 x 131 x 69 x 203 x 47 = 599203155852
Therefore, the lowest common multiple of 772,393,621,812,423 is 599203155852.
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.
772 x 393 x 621 x 812 x 423 = 64713940832016
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.
772 : 1, 2, 4, 193, 386, 772
393 : 1, 3, 131, 393
621 : 1, 3, 9, 23, 27, 69, 207, 621
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,393,621,812,423, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
393:3x 131
621:3x 3x 3x 23
812:2x 2x 7x 29
423:3x 3x 47
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 64713940832016/(1x108)
LCM = 64713940832016/108
LCM = 599203155852
Thus, we can understand that the LCM of 772,393,621,812,423 is 599203155852.
