Find LCM of 121,748,651,695,255 with Prime Factorization
| 3 | 121, 748, 651, 695, 255 |
| 5 | 121, 748, 217, 695, 85 |
| 11 | 121, 748, 217, 139, 17 |
| 17 | 11, 68, 217, 139, 17 |
| 11, 4, 217, 139, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 11 x 4 x 217 x 139 x 1 = 3722717460
Therefore, the lowest common multiple of 121,748,651,695,255 is 3722717460.
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.
121 x 748 x 651 x 695 x 255 = 10442222475300
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.
121 : 1, 11, 121
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
651 : 1, 3, 7, 21, 31, 93, 217, 651
695 : 1, 5, 139, 695
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,748,651,695,255, is 1.
Now, the common factors can be found like this.
121:11x 11
748:2x 2x 11x 17
651:3x 7x 31
695:5x 139
255:3x 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.
3x 5x 11x 17 = 2805
Therefore, the value for common factors is 2805.
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 = 10442222475300/(1x2805)
LCM = 10442222475300/2805
LCM = 3722717460
Thus, we can understand that the LCM of 121,748,651,695,255 is 3722717460.
