The LCM of 961,538,825,290,765 is 630852438150.
Find LCM of 961,538,825,290,765 with Prime Factorization
| 2 | 961, 538, 825, 290, 765 |
| 3 | 961, 269, 825, 145, 765 |
| 5 | 961, 269, 275, 145, 255 |
| 961, 269, 55, 29, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 961 x 269 x 55 x 29 x 51 = 630852438150
Therefore, the lowest common multiple of 961,538,825,290,765 is 630852438150.
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.
961 x 538 x 825 x 290 x 765 = 94627865722500
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.
961 : 1, 31, 961
538 : 1, 2, 269, 538
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
290 : 1, 2, 5, 10, 29, 58, 145, 290
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,538,825,290,765, is 1.
Now, the common factors can be found like this.
961:31x 31
538:2x 269
825:3x 5x 5x 11
290:2x 5x 29
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 94627865722500/(1x150)
LCM = 94627865722500/150
LCM = 630852438150
Thus, we can understand that the LCM of 961,538,825,290,765 is 630852438150.
