Given numbers are 155,770,847,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,770,847,970 is 25469290.
Find LCM of 155,770,847,970 with Prime Factorization
| 2 | 155, 770, 847, 970 |
| 5 | 155, 385, 847, 485 |
| 7 | 31, 77, 847, 97 |
| 11 | 31, 11, 121, 97 |
| 31, 1, 11, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 31 x 1 x 11 x 97 = 25469290
Therefore, the lowest common multiple of 155,770,847,970 is 25469290.
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.
155 x 770 x 847 x 970 = 98056766500
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.
155 : 1, 5, 31, 155
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
847 : 1, 7, 11, 77, 121, 847
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 155,770,847,970, is 1.
Now, the common factors can be found like this.
155:5x 31
770:2x 5x 7x 11
847:7x 11x 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 5x 5x 7x 11 = 3850
Therefore, the value for common factors is 3850.
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 = 98056766500/(1x3850)
LCM = 98056766500/3850
LCM = 25469290
Thus, we can understand that the LCM of 155,770,847,970 is 25469290.
