Given numbers are 278,428,135,698,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,428,135,698,620 is 86891932980.
Find LCM of 278,428,135,698,620 with Prime Factorization
| 2 | 278, 428, 135, 698, 620 |
| 2 | 139, 214, 135, 349, 310 |
| 5 | 139, 107, 135, 349, 155 |
| 139, 107, 27, 349, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 139 x 107 x 27 x 349 x 31 = 86891932980
Therefore, the lowest common multiple of 278,428,135,698,620 is 86891932980.
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 428 x 135 x 698 x 620 = 6951354638400
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
428 : 1, 2, 4, 107, 214, 428
135 : 1, 3, 5, 9, 15, 27, 45, 135
698 : 1, 2, 349, 698
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 278,428,135,698,620, is 1.
Now, the common factors can be found like this.
278:2x 139
428:2x 2x 107
135:3x 3x 3x 5
698:2x 349
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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 6951354638400/(1x80)
LCM = 6951354638400/80
LCM = 86891932980
Thus, we can understand that the LCM of 278,428,135,698,620 is 86891932980.
