Given numbers are 789,142,146,624
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,142,146,624 is 850592496.
Find LCM of 789,142,146,624 with Prime Factorization
| 2 | 789, 142, 146, 624 |
| 3 | 789, 71, 73, 312 |
| 263, 71, 73, 104 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 263 x 71 x 73 x 104 = 850592496
Therefore, the lowest common multiple of 789,142,146,624 is 850592496.
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.
789 x 142 x 146 x 624 = 10207109952
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.
789 : 1, 3, 263, 789
142 : 1, 2, 71, 142
146 : 1, 2, 73, 146
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,142,146,624, is 1.
Now, the common factors can be found like this.
789:3x 263
142:2x 71
146:2x 73
624:2x 2x 2x 2x 3x 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 3 = 12
Therefore, the value for common factors is 12.
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 = 10207109952/(1x12)
LCM = 10207109952/12
LCM = 850592496
Thus, we can understand that the LCM of 789,142,146,624 is 850592496.
