Given numbers are 816,709,421,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,709,421,122 is 14857588464.
Find LCM of 816,709,421,122 with Prime Factorization
2 | 816, 709, 421, 122 |
408, 709, 421, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 408 x 709 x 421 x 61 = 14857588464
Therefore, the lowest common multiple of 816,709,421,122 is 14857588464.
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.
816 x 709 x 421 x 122 = 29715176928
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
709 : 1, 709
421 : 1, 421
122 : 1, 2, 61, 122
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,709,421,122, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
709:709
421:421
122:2x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 29715176928/(1x2)
LCM = 29715176928/2
LCM = 14857588464
Thus, we can understand that the LCM of 816,709,421,122 is 14857588464.
