Find LCM of 639,210,574,655,441 with Prime Factorization
| 2 | 639, 210, 574, 655, 441 |
| 3 | 639, 105, 287, 655, 441 |
| 3 | 213, 35, 287, 655, 147 |
| 5 | 71, 35, 287, 655, 49 |
| 7 | 71, 7, 287, 131, 49 |
| 71, 1, 41, 131, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 71 x 1 x 41 x 131 x 7 = 1681713810
Therefore, the lowest common multiple of 639,210,574,655,441 is 1681713810.
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.
639 x 210 x 574 x 655 x 441 = 22249073706300
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.
639 : 1, 3, 9, 71, 213, 639
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
574 : 1, 2, 7, 14, 41, 82, 287, 574
655 : 1, 5, 131, 655
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,210,574,655,441, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
210:2x 3x 5x 7
574:2x 7x 41
655:5x 131
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 7x 7 = 13230
Therefore, the value for common factors is 13230.
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 = 22249073706300/(1x13230)
LCM = 22249073706300/13230
LCM = 1681713810
Thus, we can understand that the LCM of 639,210,574,655,441 is 1681713810.
