Given numbers are 900,478,980,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 900,478,980,475 is 200258100.
Find LCM of 900,478,980,475 with Prime Factorization
| 2 | 900, 478, 980, 475 |
| 2 | 450, 239, 490, 475 |
| 5 | 225, 239, 245, 475 |
| 5 | 45, 239, 49, 95 |
| 9, 239, 49, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 9 x 239 x 49 x 19 = 200258100
Therefore, the lowest common multiple of 900,478,980,475 is 200258100.
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.
900 x 478 x 980 x 475 = 200258100000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
478 : 1, 2, 239, 478
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,478,980,475, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
478:2x 239
980:2x 2x 5x 7x 7
475:5x 5x 19
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 5 = 1000
Therefore, the value for common factors is 1000.
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 = 200258100000/(1x1000)
LCM = 200258100000/1000
LCM = 200258100
Thus, we can understand that the LCM of 900,478,980,475 is 200258100.
