Given numbers are 628,574,897,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,574,897,812 is 4688479068.
Find LCM of 628,574,897,812 with Prime Factorization
2 | 628, 574, 897, 812 |
2 | 314, 287, 897, 406 |
7 | 157, 287, 897, 203 |
157, 41, 897, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 157 x 41 x 897 x 29 = 4688479068
Therefore, the lowest common multiple of 628,574,897,812 is 4688479068.
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.
628 x 574 x 897 x 812 = 262554827808
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.
628 : 1, 2, 4, 157, 314, 628
574 : 1, 2, 7, 14, 41, 82, 287, 574
897 : 1, 3, 13, 23, 39, 69, 299, 897
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,574,897,812, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
574:2x 7x 41
897:3x 13x 23
812:2x 2x 7x 29
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 7 = 56
Therefore, the value for common factors is 56.
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 = 262554827808/(1x56)
LCM = 262554827808/56
LCM = 4688479068
Thus, we can understand that the LCM of 628,574,897,812 is 4688479068.
