Given numbers are 208,678,821,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,678,821,553 is 32013364656.
Find LCM of 208,678,821,553 with Prime Factorization
2 | 208, 678, 821, 553 |
104, 339, 821, 553 |
Multiply the prime numbers at the bottom and the left side.
2 x 104 x 339 x 821 x 553 = 32013364656
Therefore, the lowest common multiple of 208,678,821,553 is 32013364656.
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.
208 x 678 x 821 x 553 = 64026729312
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
678 : 1, 2, 3, 6, 113, 226, 339, 678
821 : 1, 821
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,678,821,553, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
678:2x 3x 113
821:821
553:7x 79
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 = 64026729312/(1x2)
LCM = 64026729312/2
LCM = 32013364656
Thus, we can understand that the LCM of 208,678,821,553 is 32013364656.
