Given numbers are 278,658,578,347,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,658,578,347,388 is 1779384246724.
Find LCM of 278,658,578,347,388 with Prime Factorization
| 2 | 278, 658, 578, 347, 388 |
| 139, 329, 289, 347, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 329 x 289 x 347 x 194 = 1779384246724
Therefore, the lowest common multiple of 278,658,578,347,388 is 1779384246724.
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 658 x 578 x 347 x 388 = 14235073973792
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
658 : 1, 2, 7, 14, 47, 94, 329, 658
578 : 1, 2, 17, 34, 289, 578
347 : 1, 347
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,658,578,347,388, is 1.
Now, the common factors can be found like this.
278:2x 139
658:2x 7x 47
578:2x 17x 17
347:347
388:2x 2x 97
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 2 = 8
Therefore, the value for common factors is 8.
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 = 14235073973792/(1x8)
LCM = 14235073973792/8
LCM = 1779384246724
Thus, we can understand that the LCM of 278,658,578,347,388 is 1779384246724.
