Given numbers are 478,398,627,257,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,398,627,257,649 is 904343973522.
Find LCM of 478,398,627,257,649 with Prime Factorization
2 | 478, 398, 627, 257, 649 |
11 | 239, 199, 627, 257, 649 |
239, 199, 57, 257, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 239 x 199 x 57 x 257 x 59 = 904343973522
Therefore, the lowest common multiple of 478,398,627,257,649 is 904343973522.
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.
478 x 398 x 627 x 257 x 649 = 19895567417484
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.
478 : 1, 2, 239, 478
398 : 1, 2, 199, 398
627 : 1, 3, 11, 19, 33, 57, 209, 627
257 : 1, 257
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,398,627,257,649, is 1.
Now, the common factors can be found like this.
478:2x 239
398:2x 199
627:3x 11x 19
257:257
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 19895567417484/(1x22)
LCM = 19895567417484/22
LCM = 904343973522
Thus, we can understand that the LCM of 478,398,627,257,649 is 904343973522.
