Given numbers are 784,799,711,771,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,799,711,771,438 is 8355807499536.
Find LCM of 784,799,711,771,438 with Prime Factorization
| 2 | 784, 799, 711, 771, 438 |
| 3 | 392, 799, 711, 771, 219 |
| 392, 799, 237, 257, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 392 x 799 x 237 x 257 x 73 = 8355807499536
Therefore, the lowest common multiple of 784,799,711,771,438 is 8355807499536.
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.
784 x 799 x 711 x 771 x 438 = 150404534991648
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
799 : 1, 17, 47, 799
711 : 1, 3, 9, 79, 237, 711
771 : 1, 3, 257, 771
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,799,711,771,438, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
799:17x 47
711:3x 3x 79
771:3x 257
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 150404534991648/(1x18)
LCM = 150404534991648/18
LCM = 8355807499536
Thus, we can understand that the LCM of 784,799,711,771,438 is 8355807499536.
