Find LCM of 421,845,472,320,959 with Prime Factorization
| 2 | 421, 845, 472, 320, 959 |
| 2 | 421, 845, 236, 160, 959 |
| 2 | 421, 845, 118, 80, 959 |
| 5 | 421, 845, 59, 40, 959 |
| 421, 169, 59, 8, 959 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 421 x 169 x 59 x 8 x 959 = 1288218102080
Therefore, the lowest common multiple of 421,845,472,320,959 is 1288218102080.
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.
421 x 845 x 472 x 320 x 959 = 51528724083200
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.
421 : 1, 421
845 : 1, 5, 13, 65, 169, 845
472 : 1, 2, 4, 8, 59, 118, 236, 472
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,845,472,320,959, is 1.
Now, the common factors can be found like this.
421:421
845:5x 13x 13
472:2x 2x 2x 59
320:2x 2x 2x 2x 2x 2x 5
959:7x 137
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 51528724083200/(1x40)
LCM = 51528724083200/40
LCM = 1288218102080
Thus, we can understand that the LCM of 421,845,472,320,959 is 1288218102080.
