The LCM of 403,660,712,955,561 is 153727396680.
Find LCM of 403,660,712,955,561 with Prime Factorization
| 2 | 403, 660, 712, 955, 561 |
| 2 | 403, 330, 356, 955, 561 |
| 3 | 403, 165, 178, 955, 561 |
| 5 | 403, 55, 178, 955, 187 |
| 11 | 403, 11, 178, 191, 187 |
| 403, 1, 178, 191, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 403 x 1 x 178 x 191 x 17 = 153727396680
Therefore, the lowest common multiple of 403,660,712,955,561 is 153727396680.
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.
403 x 660 x 712 x 955 x 561 = 101460081808800
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.
403 : 1, 13, 31, 403
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
712 : 1, 2, 4, 8, 89, 178, 356, 712
955 : 1, 5, 191, 955
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,660,712,955,561, is 1.
Now, the common factors can be found like this.
403:13x 31
660:2x 2x 3x 5x 11
712:2x 2x 2x 89
955:5x 191
561:3x 11x 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 2x 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 101460081808800/(1x660)
LCM = 101460081808800/660
LCM = 153727396680
Thus, we can understand that the LCM of 403,660,712,955,561 is 153727396680.
