Find LCM of 994,142,392,153,762 with Prime Factorization
| 2 | 994, 142, 392, 153, 762 |
| 3 | 497, 71, 196, 153, 381 |
| 7 | 497, 71, 196, 51, 127 |
| 71 | 71, 71, 28, 51, 127 |
| 1, 1, 28, 51, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 71 x 1 x 1 x 28 x 51 x 127 = 540803592
Therefore, the lowest common multiple of 994,142,392,153,762 is 540803592.
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.
994 x 142 x 392 x 153 x 762 = 6450705245376
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
142 : 1, 2, 71, 142
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
153 : 1, 3, 9, 17, 51, 153
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,142,392,153,762, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
142:2x 71
392:2x 2x 2x 7x 7
153:3x 3x 17
762:2x 3x 127
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 3x 7x 71 = 11928
Therefore, the value for common factors is 11928.
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 = 6450705245376/(1x11928)
LCM = 6450705245376/11928
LCM = 540803592
Thus, we can understand that the LCM of 994,142,392,153,762 is 540803592.
