Given numbers are 278,130,360,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,130,360,417 is 650520.
Find LCM of 278,130,360,417 with Prime Factorization
| 2 | 278, 130, 360, 417 |
| 3 | 139, 65, 180, 417 |
| 5 | 139, 65, 60, 139 |
| 139 | 139, 13, 12, 139 |
| 1, 13, 12, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 139 x 1 x 13 x 12 x 1 = 650520
Therefore, the lowest common multiple of 278,130,360,417 is 650520.
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.
278 x 130 x 360 x 417 = 5425336800
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.
278 : 1, 2, 139, 278
130 : 1, 2, 5, 10, 13, 26, 65, 130
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,130,360,417, is 1.
Now, the common factors can be found like this.
278:2x 139
130:2x 5x 13
360:2x 2x 2x 3x 3x 5
417:3x 139
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 5x 139 = 8340
Therefore, the value for common factors is 8340.
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 = 5425336800/(1x8340)
LCM = 5425336800/8340
LCM = 650520
Thus, we can understand that the LCM of 278,130,360,417 is 650520.
