Given numbers are 189,434,235,655,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,434,235,655,770 is 3968124930.
Find LCM of 189,434,235,655,770 with Prime Factorization
| 2 | 189, 434, 235, 655, 770 |
| 5 | 189, 217, 235, 655, 385 |
| 7 | 189, 217, 47, 131, 77 |
| 27, 31, 47, 131, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 27 x 31 x 47 x 131 x 11 = 3968124930
Therefore, the lowest common multiple of 189,434,235,655,770 is 3968124930.
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.
189 x 434 x 235 x 655 x 770 = 9721906078500
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
434 : 1, 2, 7, 14, 31, 62, 217, 434
235 : 1, 5, 47, 235
655 : 1, 5, 131, 655
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,434,235,655,770, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
434:2x 7x 31
235:5x 47
655:5x 131
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7x 7 = 2450
Therefore, the value for common factors is 2450.
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 = 9721906078500/(1x2450)
LCM = 9721906078500/2450
LCM = 3968124930
Thus, we can understand that the LCM of 189,434,235,655,770 is 3968124930.
