Given numbers are 253,462,820,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,462,820,784 is 121986480.
Find LCM of 253,462,820,784 with Prime Factorization
| 2 | 253, 462, 820, 784 |
| 2 | 253, 231, 410, 392 |
| 7 | 253, 231, 205, 196 |
| 11 | 253, 33, 205, 28 |
| 23, 3, 205, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 23 x 3 x 205 x 28 = 121986480
Therefore, the lowest common multiple of 253,462,820,784 is 121986480.
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.
253 x 462 x 820 x 784 = 75143671680
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.
253 : 1, 11, 23, 253
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,462,820,784, is 1.
Now, the common factors can be found like this.
253:11x 23
462:2x 3x 7x 11
820:2x 2x 5x 41
784:2x 2x 2x 2x 7x 7
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 2x 7x 11 = 616
Therefore, the value for common factors is 616.
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 = 75143671680/(1x616)
LCM = 75143671680/616
LCM = 121986480
Thus, we can understand that the LCM of 253,462,820,784 is 121986480.
