Given numbers are 842,507,278,78
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,507,278,78 is 59338266.
Find LCM of 842,507,278,78 with Prime Factorization
2 | 842, 507, 278, 78 |
3 | 421, 507, 139, 39 |
13 | 421, 169, 139, 13 |
421, 1, 139, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 421 x 1 x 139 x 13 = 59338266
Therefore, the lowest common multiple of 842,507,278,78 is 59338266.
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.
842 x 507 x 278 x 78 = 9256769496
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.
842 : 1, 2, 421, 842
507 : 1, 3, 13, 39, 169, 507
278 : 1, 2, 139, 278
78 : 1, 2, 3, 6, 13, 26, 39, 78
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,507,278,78, is 1.
Now, the common factors can be found like this.
842:2x 421
507:3x 13x 13
278:2x 139
78:2x 3x 13
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 9256769496/(1x156)
LCM = 9256769496/156
LCM = 59338266
Thus, we can understand that the LCM of 842,507,278,78 is 59338266.
