Given numbers are 278,622,392,728,718
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,622,392,728,718 is 79085899256.
Find LCM of 278,622,392,728,718 with Prime Factorization
| 2 | 278, 622, 392, 728, 718 |
| 2 | 139, 311, 196, 364, 359 |
| 2 | 139, 311, 98, 182, 359 |
| 7 | 139, 311, 49, 91, 359 |
| 139, 311, 7, 13, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 139 x 311 x 7 x 13 x 359 = 79085899256
Therefore, the lowest common multiple of 278,622,392,728,718 is 79085899256.
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 622 x 392 x 728 x 718 = 35430482866688
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
622 : 1, 2, 311, 622
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
718 : 1, 2, 359, 718
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,622,392,728,718, is 2.
Now, the common factors can be found like this.
278:2x 139
622:2x 311
392:2x 2x 2x 7x 7
728:2x 2x 2x 7x 13
718:2x 359
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 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 35430482866688/(2x224)
LCM = 35430482866688/448
LCM = 79085899256
Thus, we can understand that the LCM of 278,622,392,728,718 is 79085899256.
