Given numbers are 378,417,150,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,417,150,620 is 81440100.
Find LCM of 378,417,150,620 with Prime Factorization
| 2 | 378, 417, 150, 620 |
| 3 | 189, 417, 75, 310 |
| 5 | 63, 139, 25, 310 |
| 63, 139, 5, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 63 x 139 x 5 x 62 = 81440100
Therefore, the lowest common multiple of 378,417,150,620 is 81440100.
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.
378 x 417 x 150 x 620 = 14659218000
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
417 : 1, 3, 139, 417
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,417,150,620, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
417:3x 139
150:2x 3x 5x 5
620:2x 2x 5x 31
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 5 = 180
Therefore, the value for common factors is 180.
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 = 14659218000/(1x180)
LCM = 14659218000/180
LCM = 81440100
Thus, we can understand that the LCM of 378,417,150,620 is 81440100.
