The LCM of 278,880,407,555 is 13577520.
Find LCM of 278,880,407,555 with Prime Factorization
| 2 | 278, 880, 407, 555 |
| 5 | 139, 440, 407, 555 |
| 11 | 139, 88, 407, 111 |
| 37 | 139, 8, 37, 111 |
| 139, 8, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 37 x 139 x 8 x 1 x 3 = 13577520
Therefore, the lowest common multiple of 278,880,407,555 is 13577520.
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 880 x 407 x 555 = 55260506400
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
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
407 : 1, 11, 37, 407
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,880,407,555, is 1.
Now, the common factors can be found like this.
278:2x 139
880:2x 2x 2x 2x 5x 11
407:11x 37
555:3x 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 5x 11x 37 = 4070
Therefore, the value for common factors is 4070.
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 = 55260506400/(1x4070)
LCM = 55260506400/4070
LCM = 13577520
Thus, we can understand that the LCM of 278,880,407,555 is 13577520.
