Find LCM of 136,490,147,928,763 with Prime Factorization
| 2 | 136, 490, 147, 928, 763 |
| 2 | 68, 245, 147, 464, 763 |
| 2 | 34, 245, 147, 232, 763 |
| 7 | 17, 245, 147, 116, 763 |
| 7 | 17, 35, 21, 116, 109 |
| 17, 5, 3, 116, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 17 x 5 x 3 x 116 x 109 = 1263894240
Therefore, the lowest common multiple of 136,490,147,928,763 is 1263894240.
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.
136 x 490 x 147 x 928 x 763 = 6936251589120
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.
136 : 1, 2, 4, 8, 17, 34, 68, 136
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
147 : 1, 3, 7, 21, 49, 147
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 136,490,147,928,763, is 1.
Now, the common factors can be found like this.
136:2x 2x 2x 17
490:2x 5x 7x 7
147:3x 7x 7
928:2x 2x 2x 2x 2x 29
763:7x 109
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 2x 2x 7x 7x 7 = 5488
Therefore, the value for common factors is 5488.
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 = 6936251589120/(1x5488)
LCM = 6936251589120/5488
LCM = 1263894240
Thus, we can understand that the LCM of 136,490,147,928,763 is 1263894240.
