The LCM of 157,242,946,988,493 is 397884794164.
Find LCM of 157,242,946,988,493 with Prime Factorization
| 2 | 157, 242, 946, 988, 493 |
| 11 | 157, 121, 473, 494, 493 |
| 157, 11, 43, 494, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 157 x 11 x 43 x 494 x 493 = 397884794164
Therefore, the lowest common multiple of 157,242,946,988,493 is 397884794164.
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.
157 x 242 x 946 x 988 x 493 = 17506930943216
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.
157 : 1, 157
242 : 1, 2, 11, 22, 121, 242
946 : 1, 2, 11, 22, 43, 86, 473, 946
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,242,946,988,493, is 1.
Now, the common factors can be found like this.
157:157
242:2x 11x 11
946:2x 11x 43
988:2x 2x 13x 19
493:17x 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 11 = 44
Therefore, the value for common factors is 44.
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 = 17506930943216/(1x44)
LCM = 17506930943216/44
LCM = 397884794164
Thus, we can understand that the LCM of 157,242,946,988,493 is 397884794164.
