The LCM of 442,390,786,603,655 is 174574530.
Find LCM of 442,390,786,603,655 with Prime Factorization
| 2 | 442, 390, 786, 603, 655 |
| 3 | 221, 195, 393, 603, 655 |
| 5 | 221, 65, 131, 201, 655 |
| 13 | 221, 13, 131, 201, 131 |
| 131 | 17, 1, 131, 201, 131 |
| 17, 1, 1, 201, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 131 x 17 x 1 x 1 x 201 x 1 = 174574530
Therefore, the lowest common multiple of 442,390,786,603,655 is 174574530.
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.
442 x 390 x 786 x 603 x 655 = 53514076426200
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
786 : 1, 2, 3, 6, 131, 262, 393, 786
603 : 1, 3, 9, 67, 201, 603
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,390,786,603,655, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
390:2x 3x 5x 13
786:2x 3x 131
603:3x 3x 67
655:5x 131
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 3x 5x 13x 131 = 306540
Therefore, the value for common factors is 306540.
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 = 53514076426200/(1x306540)
LCM = 53514076426200/306540
LCM = 174574530
Thus, we can understand that the LCM of 442,390,786,603,655 is 174574530.
