The LCM of 456,754,551,947 is 162800664.
Find LCM of 456,754,551,947 with Prime Factorization
| 2 | 456, 754, 551, 947 |
| 19 | 228, 377, 551, 947 |
| 29 | 12, 377, 29, 947 |
| 12, 13, 1, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 29 x 12 x 13 x 1 x 947 = 162800664
Therefore, the lowest common multiple of 456,754,551,947 is 162800664.
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.
456 x 754 x 551 x 947 = 179406331728
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
754 : 1, 2, 13, 26, 29, 58, 377, 754
551 : 1, 19, 29, 551
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,754,551,947, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
754:2x 13x 29
551:19x 29
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 29 = 1102
Therefore, the value for common factors is 1102.
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 = 179406331728/(1x1102)
LCM = 179406331728/1102
LCM = 162800664
Thus, we can understand that the LCM of 456,754,551,947 is 162800664.
