Find LCM of 409,471,780,676,143 with Prime Factorization
2 | 409, 471, 780, 676, 143 |
2 | 409, 471, 390, 338, 143 |
3 | 409, 471, 195, 169, 143 |
13 | 409, 157, 65, 169, 143 |
409, 157, 5, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 409 x 157 x 5 x 13 x 11 = 7162318020
Therefore, the lowest common multiple of 409,471,780,676,143 is 7162318020.
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.
409 x 471 x 780 x 676 x 143 = 14525180944560
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.
409 : 1, 409
471 : 1, 3, 157, 471
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,471,780,676,143, is 1.
Now, the common factors can be found like this.
409:409
471:3x 157
780:2x 2x 3x 5x 13
676:2x 2x 13x 13
143:11x 13
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 13x 13 = 2028
Therefore, the value for common factors is 2028.
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 = 14525180944560/(1x2028)
LCM = 14525180944560/2028
LCM = 7162318020
Thus, we can understand that the LCM of 409,471,780,676,143 is 7162318020.
