Find LCM of 790,209,570,474 with Prime Factorization
| 2 | 790, 209, 570, 474 |
| 3 | 395, 209, 285, 237 |
| 5 | 395, 209, 95, 79 |
| 19 | 79, 209, 19, 79 |
| 79 | 79, 11, 1, 79 |
| 1, 11, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 79 x 1 x 11 x 1 x 1 = 495330
Therefore, the lowest common multiple of 790,209,570,474 is 495330.
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.
790 x 209 x 570 x 474 = 44609419800
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
209 : 1, 11, 19, 209
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,209,570,474, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
209:11x 19
570:2x 3x 5x 19
474:2x 3x 79
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 5x 19x 79 = 90060
Therefore, the value for common factors is 90060.
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 = 44609419800/(1x90060)
LCM = 44609419800/90060
LCM = 495330
Thus, we can understand that the LCM of 790,209,570,474 is 495330.
