Given numbers are 983,399,385,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 983,399,385,972 is 6989306940.
Find LCM of 983,399,385,972 with Prime Factorization
3 | 983, 399, 385, 972 |
7 | 983, 133, 385, 324 |
983, 19, 55, 324 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 983 x 19 x 55 x 324 = 6989306940
Therefore, the lowest common multiple of 983,399,385,972 is 6989306940.
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.
983 x 399 x 385 x 972 = 146775445740
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.
983 : 1, 983
399 : 1, 3, 7, 19, 21, 57, 133, 399
385 : 1, 5, 7, 11, 35, 55, 77, 385
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,399,385,972, is 1.
Now, the common factors can be found like this.
983:983
399:3x 7x 19
385:5x 7x 11
972:2x 2x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 146775445740/(1x21)
LCM = 146775445740/21
LCM = 6989306940
Thus, we can understand that the LCM of 983,399,385,972 is 6989306940.
