Find LCM of 535,690,264,642,391 with Prime Factorization
| 2 | 535, 690, 264, 642, 391 |
| 3 | 535, 345, 132, 321, 391 |
| 5 | 535, 115, 44, 107, 391 |
| 23 | 107, 23, 44, 107, 391 |
| 107 | 107, 1, 44, 107, 17 |
| 1, 1, 44, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 107 x 1 x 1 x 44 x 1 x 17 = 55224840
Therefore, the lowest common multiple of 535,690,264,642,391 is 55224840.
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.
535 x 690 x 264 x 642 x 391 = 24463499623200
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.
535 : 1, 5, 107, 535
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
642 : 1, 2, 3, 6, 107, 214, 321, 642
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 535,690,264,642,391, is 1.
Now, the common factors can be found like this.
535:5x 107
690:2x 3x 5x 23
264:2x 2x 2x 3x 11
642:2x 3x 107
391:17x 23
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 23x 107 = 442980
Therefore, the value for common factors is 442980.
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 = 24463499623200/(1x442980)
LCM = 24463499623200/442980
LCM = 55224840
Thus, we can understand that the LCM of 535,690,264,642,391 is 55224840.
