Find LCM of 983,891,630,415,438 with Prime Factorization
2 | 983, 891, 630, 415, 438 |
3 | 983, 891, 315, 415, 219 |
3 | 983, 297, 105, 415, 73 |
5 | 983, 99, 35, 415, 73 |
983, 99, 7, 83, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 983 x 99 x 7 x 83 x 73 = 371475532890
Therefore, the lowest common multiple of 983,891,630,415,438 is 371475532890.
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 891 x 630 x 415 x 438 = 100298393880300
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
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
415 : 1, 5, 83, 415
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,891,630,415,438, is 1.
Now, the common factors can be found like this.
983:983
891:3x 3x 3x 3x 11
630:2x 3x 3x 5x 7
415:5x 83
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 100298393880300/(1x270)
LCM = 100298393880300/270
LCM = 371475532890
Thus, we can understand that the LCM of 983,891,630,415,438 is 371475532890.
