Given numbers are 147,981,764,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 147,981,764,228 is 697769604.
Find LCM of 147,981,764,228 with Prime Factorization
| 2 | 147, 981, 764, 228 |
| 2 | 147, 981, 382, 114 |
| 3 | 147, 981, 191, 57 |
| 49, 327, 191, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 49 x 327 x 191 x 19 = 697769604
Therefore, the lowest common multiple of 147,981,764,228 is 697769604.
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.
147 x 981 x 764 x 228 = 25119705744
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.
147 : 1, 3, 7, 21, 49, 147
981 : 1, 3, 9, 109, 327, 981
764 : 1, 2, 4, 191, 382, 764
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,981,764,228, is 1.
Now, the common factors can be found like this.
147:3x 7x 7
981:3x 3x 109
764:2x 2x 191
228:2x 2x 3x 19
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 3 = 36
Therefore, the value for common factors is 36.
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 = 25119705744/(1x36)
LCM = 25119705744/36
LCM = 697769604
Thus, we can understand that the LCM of 147,981,764,228 is 697769604.
