The LCM of 658,561,885,740,490 is 56407977780.
Find LCM of 658,561,885,740,490 with Prime Factorization
| 2 | 658, 561, 885, 740, 490 |
| 3 | 329, 561, 885, 370, 245 |
| 5 | 329, 187, 295, 370, 245 |
| 7 | 329, 187, 59, 74, 49 |
| 47, 187, 59, 74, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 47 x 187 x 59 x 74 x 7 = 56407977780
Therefore, the lowest common multiple of 658,561,885,740,490 is 56407977780.
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.
658 x 561 x 885 x 740 x 490 = 118456753338000
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
561 : 1, 3, 11, 17, 33, 51, 187, 561
885 : 1, 3, 5, 15, 59, 177, 295, 885
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,561,885,740,490, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
561:3x 11x 17
885:3x 5x 59
740:2x 2x 5x 37
490:2x 5x 7x 7
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 5x 7 = 2100
Therefore, the value for common factors is 2100.
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 = 118456753338000/(1x2100)
LCM = 118456753338000/2100
LCM = 56407977780
Thus, we can understand that the LCM of 658,561,885,740,490 is 56407977780.
