Find LCM of 248,747,472,913,780 with Prime Factorization
| 2 | 248, 747, 472, 913, 780 |
| 2 | 124, 747, 236, 913, 390 |
| 2 | 62, 747, 118, 913, 195 |
| 3 | 31, 747, 59, 913, 195 |
| 83 | 31, 249, 59, 913, 65 |
| 31, 3, 59, 11, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 83 x 31 x 3 x 59 x 11 x 65 = 7815024360
Therefore, the lowest common multiple of 248,747,472,913,780 is 7815024360.
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.
248 x 747 x 472 x 913 x 780 = 62270114100480
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
747 : 1, 3, 9, 83, 249, 747
472 : 1, 2, 4, 8, 59, 118, 236, 472
913 : 1, 11, 83, 913
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 248,747,472,913,780, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
747:3x 3x 83
472:2x 2x 2x 59
913:11x 83
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 2x 2x 2x 3x 83 = 7968
Therefore, the value for common factors is 7968.
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 = 62270114100480/(1x7968)
LCM = 62270114100480/7968
LCM = 7815024360
Thus, we can understand that the LCM of 248,747,472,913,780 is 7815024360.
