Given numbers are 771,805,230,220,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 771,805,230,220,970 is 2648955540.
Find LCM of 771,805,230,220,970 with Prime Factorization
| 2 | 771, 805, 230, 220, 970 |
| 5 | 771, 805, 115, 110, 485 |
| 23 | 771, 161, 23, 22, 97 |
| 771, 7, 1, 22, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 771 x 7 x 1 x 22 x 97 = 2648955540
Therefore, the lowest common multiple of 771,805,230,220,970 is 2648955540.
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.
771 x 805 x 230 x 220 x 970 = 30462988710000
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.
771 : 1, 3, 257, 771
805 : 1, 5, 7, 23, 35, 115, 161, 805
230 : 1, 2, 5, 10, 23, 46, 115, 230
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,805,230,220,970, is 1.
Now, the common factors can be found like this.
771:3x 257
805:5x 7x 23
230:2x 5x 23
220:2x 2x 5x 11
970:2x 5x 97
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 5x 5x 5x 23 = 11500
Therefore, the value for common factors is 11500.
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 = 30462988710000/(1x11500)
LCM = 30462988710000/11500
LCM = 2648955540
Thus, we can understand that the LCM of 771,805,230,220,970 is 2648955540.
