Given numbers are 120,759,411,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,759,411,788 is 819386040.
Find LCM of 120,759,411,788 with Prime Factorization
2 | 120, 759, 411, 788 |
2 | 60, 759, 411, 394 |
3 | 30, 759, 411, 197 |
10, 253, 137, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 10 x 253 x 137 x 197 = 819386040
Therefore, the lowest common multiple of 120,759,411,788 is 819386040.
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.
120 x 759 x 411 x 788 = 29497897440
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
759 : 1, 3, 11, 23, 33, 69, 253, 759
411 : 1, 3, 137, 411
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,759,411,788, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
759:3x 11x 23
411:3x 137
788:2x 2x 197
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 3 = 36
Therefore, the value for common factors is 36.
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 = 29497897440/(1x36)
LCM = 29497897440/36
LCM = 819386040
Thus, we can understand that the LCM of 120,759,411,788 is 819386040.
