Find LCM of 307,251,139,480,780 with Prime Factorization
| 2 | 307, 251, 139, 480, 780 |
| 2 | 307, 251, 139, 240, 390 |
| 3 | 307, 251, 139, 120, 195 |
| 5 | 307, 251, 139, 40, 65 |
| 307, 251, 139, 8, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 307 x 251 x 139 x 8 x 13 = 66836159520
Therefore, the lowest common multiple of 307,251,139,480,780 is 66836159520.
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.
307 x 251 x 139 x 480 x 780 = 4010169571200
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.
307 : 1, 307
251 : 1, 251
139 : 1, 139
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,251,139,480,780, is 1.
Now, the common factors can be found like this.
307:307
251:251
139:139
480:2x 2x 2x 2x 2x 3x 5
780:2x 2x 3x 5x 13
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 5 = 60
Therefore, the value for common factors is 60.
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 = 4010169571200/(1x60)
LCM = 4010169571200/60
LCM = 66836159520
Thus, we can understand that the LCM of 307,251,139,480,780 is 66836159520.
