Find LCM of 842,595,495,747,421 with Prime Factorization
| 3 | 842, 595, 495, 747, 421 |
| 3 | 842, 595, 165, 249, 421 |
| 5 | 842, 595, 55, 83, 421 |
| 421 | 842, 119, 11, 83, 421 |
| 2, 119, 11, 83, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 421 x 2 x 119 x 11 x 83 x 1 = 4116634830
Therefore, the lowest common multiple of 842,595,495,747,421 is 4116634830.
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.
842 x 595 x 495 x 747 x 421 = 77989646854350
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.
842 : 1, 2, 421, 842
595 : 1, 5, 7, 17, 35, 85, 119, 595
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
747 : 1, 3, 9, 83, 249, 747
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,595,495,747,421, is 1.
Now, the common factors can be found like this.
842:2x 421
595:5x 7x 17
495:3x 3x 5x 11
747:3x 3x 83
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 421 = 18945
Therefore, the value for common factors is 18945.
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 = 77989646854350/(1x18945)
LCM = 77989646854350/18945
LCM = 4116634830
Thus, we can understand that the LCM of 842,595,495,747,421 is 4116634830.
