Find LCM of 781,624,708,360,789 with Prime Factorization
| 2 | 781, 624, 708, 360, 789 |
| 2 | 781, 312, 354, 180, 789 |
| 2 | 781, 156, 177, 90, 789 |
| 3 | 781, 78, 177, 45, 789 |
| 781, 26, 59, 15, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 781 x 26 x 59 x 15 x 263 = 113431752720
Therefore, the lowest common multiple of 781,624,708,360,789 is 113431752720.
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.
781 x 624 x 708 x 360 x 789 = 98005034350080
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.
781 : 1, 11, 71, 781
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,624,708,360,789, is 1.
Now, the common factors can be found like this.
781:11x 71
624:2x 2x 2x 2x 3x 13
708:2x 2x 3x 59
360:2x 2x 2x 3x 3x 5
789:3x 263
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 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 98005034350080/(1x864)
LCM = 98005034350080/864
LCM = 113431752720
Thus, we can understand that the LCM of 781,624,708,360,789 is 113431752720.
