The LCM of 860,972,693,889 is 2043615420.
Find LCM of 860,972,693,889 with Prime Factorization
| 2 | 860, 972, 693, 889 |
| 2 | 430, 486, 693, 889 |
| 3 | 215, 243, 693, 889 |
| 3 | 215, 81, 231, 889 |
| 7 | 215, 27, 77, 889 |
| 215, 27, 11, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 215 x 27 x 11 x 127 = 2043615420
Therefore, the lowest common multiple of 860,972,693,889 is 2043615420.
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.
860 x 972 x 693 x 889 = 514991085840
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,972,693,889, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
972:2x 2x 3x 3x 3x 3x 3
693:3x 3x 7x 11
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 514991085840/(1x252)
LCM = 514991085840/252
LCM = 2043615420
Thus, we can understand that the LCM of 860,972,693,889 is 2043615420.
