Given numbers are 989,777,878,692,865
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,777,878,692,865 is 1167233999820.
Find LCM of 989,777,878,692,865 with Prime Factorization
2 | 989, 777, 878, 692, 865 |
173 | 989, 777, 439, 346, 865 |
989, 777, 439, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 173 x 989 x 777 x 439 x 2 x 5 = 1167233999820
Therefore, the lowest common multiple of 989,777,878,692,865 is 1167233999820.
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.
989 x 777 x 878 x 692 x 865 = 403862963937720
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.
989 : 1, 23, 43, 989
777 : 1, 3, 7, 21, 37, 111, 259, 777
878 : 1, 2, 439, 878
692 : 1, 2, 4, 173, 346, 692
865 : 1, 5, 173, 865
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,777,878,692,865, is 1.
Now, the common factors can be found like this.
989:23x 43
777:3x 7x 37
878:2x 439
692:2x 2x 173
865:5x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 173 = 346
Therefore, the value for common factors is 346.
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 = 403862963937720/(1x346)
LCM = 403862963937720/346
LCM = 1167233999820
Thus, we can understand that the LCM of 989,777,878,692,865 is 1167233999820.
