Given numbers are 920,918,925,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,918,925,740 is 78121800.
Find LCM of 920,918,925,740 with Prime Factorization
| 2 | 920, 918, 925, 740 |
| 2 | 460, 459, 925, 370 |
| 5 | 230, 459, 925, 185 |
| 37 | 46, 459, 37, 185 |
| 46, 459, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 46 x 459 x 1 x 5 = 78121800
Therefore, the lowest common multiple of 920,918,925,740 is 78121800.
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.
920 x 918 x 925 x 740 = 578101320000
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
925 : 1, 5, 25, 37, 185, 925
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,918,925,740, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
918:2x 3x 3x 3x 17
925:5x 5x 37
740:2x 2x 5x 37
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 5x 5x 37 = 7400
Therefore, the value for common factors is 7400.
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 = 578101320000/(1x7400)
LCM = 578101320000/7400
LCM = 78121800
Thus, we can understand that the LCM of 920,918,925,740 is 78121800.
