Find LCM of 196,780,620,878,301 with Prime Factorization
| 2 | 196, 780, 620, 878, 301 |
| 2 | 98, 390, 310, 439, 301 |
| 5 | 49, 195, 155, 439, 301 |
| 7 | 49, 39, 31, 439, 301 |
| 7, 39, 31, 439, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 7 x 39 x 31 x 439 x 43 = 22365847140
Therefore, the lowest common multiple of 196,780,620,878,301 is 22365847140.
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.
196 x 780 x 620 x 878 x 301 = 25049748796800
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.
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
878 : 1, 2, 439, 878
301 : 1, 7, 43, 301
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,780,620,878,301, is 1.
Now, the common factors can be found like this.
196:2x 2x 7x 7
780:2x 2x 3x 5x 13
620:2x 2x 5x 31
878:2x 439
301:7x 43
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 2x 2x 5x 7 = 1120
Therefore, the value for common factors is 1120.
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 = 25049748796800/(1x1120)
LCM = 25049748796800/1120
LCM = 22365847140
Thus, we can understand that the LCM of 196,780,620,878,301 is 22365847140.
