The LCM of 661,958,120,120 is 37994280.
Find LCM of 661,958,120,120 with Prime Factorization
2 | 661, 958, 120, 120 |
2 | 661, 479, 60, 60 |
2 | 661, 479, 30, 30 |
3 | 661, 479, 15, 15 |
5 | 661, 479, 5, 5 |
661, 479, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 661 x 479 x 1 x 1 = 37994280
Therefore, the lowest common multiple of 661,958,120,120 is 37994280.
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.
661 x 958 x 120 x 120 = 9118627200
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.
661 : 1, 661
958 : 1, 2, 479, 958
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,958,120,120, is 1.
Now, the common factors can be found like this.
661:661
958:2x 479
120:2x 2x 2x 3x 5
120:2x 2x 2x 3x 5
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 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 9118627200/(1x240)
LCM = 9118627200/240
LCM = 37994280
Thus, we can understand that the LCM of 661,958,120,120 is 37994280.
