Given numbers are 784,851,667,972,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,851,667,972,218 is 512479375632.
Find LCM of 784,851,667,972,218 with Prime Factorization
| 2 | 784, 851, 667, 972, 218 |
| 2 | 392, 851, 667, 486, 109 |
| 23 | 196, 851, 667, 243, 109 |
| 196, 37, 29, 243, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 196 x 37 x 29 x 243 x 109 = 512479375632
Therefore, the lowest common multiple of 784,851,667,972,218 is 512479375632.
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 851 x 667 x 972 x 218 = 94296205116288
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
851 : 1, 23, 37, 851
667 : 1, 23, 29, 667
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,851,667,972,218, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
851:23x 37
667:23x 29
972:2x 2x 3x 3x 3x 3x 3
218:2x 109
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 23 = 184
Therefore, the value for common factors is 184.
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 = 94296205116288/(1x184)
LCM = 94296205116288/184
LCM = 512479375632
Thus, we can understand that the LCM of 784,851,667,972,218 is 512479375632.
