Find LCM of 309,931,955,336,470 with Prime Factorization
| 2 | 309, 931, 955, 336, 470 |
| 3 | 309, 931, 955, 168, 235 |
| 5 | 103, 931, 955, 56, 235 |
| 7 | 103, 931, 191, 56, 47 |
| 103, 133, 191, 8, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 103 x 133 x 191 x 8 x 47 = 206599550640
Therefore, the lowest common multiple of 309,931,955,336,470 is 206599550640.
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.
309 x 931 x 955 x 336 x 470 = 43385905634400
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.
309 : 1, 3, 103, 309
931 : 1, 7, 19, 49, 133, 931
955 : 1, 5, 191, 955
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,931,955,336,470, is 1.
Now, the common factors can be found like this.
309:3x 103
931:7x 7x 19
955:5x 191
336:2x 2x 2x 2x 3x 7
470:2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 43385905634400/(1x210)
LCM = 43385905634400/210
LCM = 206599550640
Thus, we can understand that the LCM of 309,931,955,336,470 is 206599550640.
