Find LCM of 624,905,785,923,484 with Prime Factorization
| 2 | 624, 905, 785, 923, 484 |
| 2 | 312, 905, 785, 923, 242 |
| 5 | 156, 905, 785, 923, 121 |
| 13 | 156, 181, 157, 923, 121 |
| 12, 181, 157, 71, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 12 x 181 x 157 x 71 x 121 = 761686994640
Therefore, the lowest common multiple of 624,905,785,923,484 is 761686994640.
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.
624 x 905 x 785 x 923 x 484 = 198038618606400
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
905 : 1, 5, 181, 905
785 : 1, 5, 157, 785
923 : 1, 13, 71, 923
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,905,785,923,484, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
905:5x 181
785:5x 157
923:13x 71
484:2x 2x 11x 11
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 198038618606400/(1x260)
LCM = 198038618606400/260
LCM = 761686994640
Thus, we can understand that the LCM of 624,905,785,923,484 is 761686994640.
