Given numbers are 987,851,221,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,851,221,338 is 4826278002.
Find LCM of 987,851,221,338 with Prime Factorization
13 | 987, 851, 221, 338 |
987, 851, 17, 26 |
Multiply the prime numbers at the bottom and the left side.
13 x 987 x 851 x 17 x 26 = 4826278002
Therefore, the lowest common multiple of 987,851,221,338 is 4826278002.
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.
987 x 851 x 221 x 338 = 62741614026
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
851 : 1, 23, 37, 851
221 : 1, 13, 17, 221
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,851,221,338, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
851:23x 37
221:13x 17
338:2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 62741614026/(1x13)
LCM = 62741614026/13
LCM = 4826278002
Thus, we can understand that the LCM of 987,851,221,338 is 4826278002.
