Given numbers are 789,980,450,685,354
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,980,450,685,354 is 93749058900.
Find LCM of 789,980,450,685,354 with Prime Factorization
| 2 | 789, 980, 450, 685, 354 |
| 3 | 789, 490, 225, 685, 177 |
| 5 | 263, 490, 75, 685, 59 |
| 263, 98, 15, 137, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 263 x 98 x 15 x 137 x 59 = 93749058900
Therefore, the lowest common multiple of 789,980,450,685,354 is 93749058900.
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 980 x 450 x 685 x 354 = 84374153010000
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
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
685 : 1, 5, 137, 685
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,980,450,685,354, is 1.
Now, the common factors can be found like this.
789:3x 263
980:2x 2x 5x 7x 7
450:2x 3x 3x 5x 5
685:5x 137
354:2x 3x 59
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 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 84374153010000/(1x900)
LCM = 84374153010000/900
LCM = 93749058900
Thus, we can understand that the LCM of 789,980,450,685,354 is 93749058900.
