Find LCM of 773,456,551,812 with Prime Factorization
| 2 | 773, 456, 551, 812 |
| 2 | 773, 228, 551, 406 |
| 19 | 773, 114, 551, 203 |
| 29 | 773, 6, 29, 203 |
| 773, 6, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 29 x 773 x 6 x 1 x 7 = 71555064
Therefore, the lowest common multiple of 773,456,551,812 is 71555064.
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.
773 x 456 x 551 x 812 = 157707361056
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.
773 : 1, 773
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
551 : 1, 19, 29, 551
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,456,551,812, is 1.
Now, the common factors can be found like this.
773:773
456:2x 2x 2x 3x 19
551:19x 29
812:2x 2x 7x 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 19x 29 = 2204
Therefore, the value for common factors is 2204.
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 = 157707361056/(1x2204)
LCM = 157707361056/2204
LCM = 71555064
Thus, we can understand that the LCM of 773,456,551,812 is 71555064.
