The LCM of 552,991,902,138 is 246711432.
Find LCM of 552,991,902,138 with Prime Factorization
| 2 | 552, 991, 902, 138 |
| 3 | 276, 991, 451, 69 |
| 23 | 92, 991, 451, 23 |
| 4, 991, 451, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 4 x 991 x 451 x 1 = 246711432
Therefore, the lowest common multiple of 552,991,902,138 is 246711432.
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.
552 x 991 x 902 x 138 = 68092355232
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.
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
991 : 1, 991
902 : 1, 2, 11, 22, 41, 82, 451, 902
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 552,991,902,138, is 1.
Now, the common factors can be found like this.
552:2x 2x 2x 3x 23
991:991
902:2x 11x 41
138:2x 3x 23
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 3x 23 = 276
Therefore, the value for common factors is 276.
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 = 68092355232/(1x276)
LCM = 68092355232/276
LCM = 246711432
Thus, we can understand that the LCM of 552,991,902,138 is 246711432.
