The LCM of 573,442,390,580 is 73447140.
Find LCM of 573,442,390,580 with Prime Factorization
| 2 | 573, 442, 390, 580 |
| 3 | 573, 221, 195, 290 |
| 5 | 191, 221, 65, 290 |
| 13 | 191, 221, 13, 58 |
| 191, 17, 1, 58 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 191 x 17 x 1 x 58 = 73447140
Therefore, the lowest common multiple of 573,442,390,580 is 73447140.
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.
573 x 442 x 390 x 580 = 57288769200
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.
573 : 1, 3, 191, 573
442 : 1, 2, 13, 17, 26, 34, 221, 442
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 573,442,390,580, is 1.
Now, the common factors can be found like this.
573:3x 191
442:2x 13x 17
390:2x 3x 5x 13
580:2x 2x 5x 29
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 13 = 780
Therefore, the value for common factors is 780.
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 = 57288769200/(1x780)
LCM = 57288769200/780
LCM = 73447140
Thus, we can understand that the LCM of 573,442,390,580 is 73447140.
