Given numbers are 678,611,424
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,611,424 is 87822696.
Find LCM of 678,611,424 with Prime Factorization
2 | 678, 611, 424 |
339, 611, 212 |
Multiply the prime numbers at the bottom and the left side.
2 x 339 x 611 x 212 = 87822696
Therefore, the lowest common multiple of 678,611,424 is 87822696.
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.
678 x 611 x 424 = 175645392
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
611 : 1, 13, 47, 611
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,611,424, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
611:13x 47
424:2x 2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 175645392/(1x2)
LCM = 175645392/2
LCM = 87822696
Thus, we can understand that the LCM of 678,611,424 is 87822696.
