Given numbers are 274,784,203,845,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 274,784,203,845,830 is 218458742320.
Find LCM of 274,784,203,845,830 with Prime Factorization
| 2 | 274, 784, 203, 845, 830 |
| 5 | 137, 392, 203, 845, 415 |
| 7 | 137, 392, 203, 169, 83 |
| 137, 56, 29, 169, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 137 x 56 x 29 x 169 x 83 = 218458742320
Therefore, the lowest common multiple of 274,784,203,845,830 is 218458742320.
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.
274 x 784 x 203 x 845 x 830 = 30584223924800
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.
274 : 1, 2, 137, 274
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
203 : 1, 7, 29, 203
845 : 1, 5, 13, 65, 169, 845
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 274,784,203,845,830, is 1.
Now, the common factors can be found like this.
274:2x 137
784:2x 2x 2x 2x 7x 7
203:7x 29
845:5x 13x 13
830:2x 5x 83
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 30584223924800/(1x140)
LCM = 30584223924800/140
LCM = 218458742320
Thus, we can understand that the LCM of 274,784,203,845,830 is 218458742320.
