Given numbers are 768,989,989,641,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,989,989,641,437 is 9250583808.
Find LCM of 768,989,989,641,437 with Prime Factorization
23 | 768, 989, 989, 641, 437 |
43 | 768, 43, 43, 641, 19 |
768, 1, 1, 641, 19 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 768 x 1 x 1 x 641 x 19 = 9250583808
Therefore, the lowest common multiple of 768,989,989,641,437 is 9250583808.
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.
768 x 989 x 989 x 641 x 437 = 210423029880576
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
989 : 1, 23, 43, 989
989 : 1, 23, 43, 989
641 : 1, 641
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,989,989,641,437, is 1.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
989:23x 43
989:23x 43
641:641
437:19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23x 43 = 22747
Therefore, the value for common factors is 22747.
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 = 210423029880576/(1x22747)
LCM = 210423029880576/22747
LCM = 9250583808
Thus, we can understand that the LCM of 768,989,989,641,437 is 9250583808.
