Find LCM of 781,182,525,698,285 with Prime Factorization
| 2 | 781, 182, 525, 698, 285 |
| 3 | 781, 91, 525, 349, 285 |
| 5 | 781, 91, 175, 349, 95 |
| 7 | 781, 91, 35, 349, 19 |
| 781, 13, 5, 349, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 781 x 13 x 5 x 349 x 19 = 70690770150
Therefore, the lowest common multiple of 781,182,525,698,285 is 70690770150.
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.
781 x 182 x 525 x 698 x 285 = 14845061731500
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.
781 : 1, 11, 71, 781
182 : 1, 2, 7, 13, 14, 26, 91, 182
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
698 : 1, 2, 349, 698
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,182,525,698,285, is 1.
Now, the common factors can be found like this.
781:11x 71
182:2x 7x 13
525:3x 5x 5x 7
698:2x 349
285:3x 5x 19
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 14845061731500/(1x210)
LCM = 14845061731500/210
LCM = 70690770150
Thus, we can understand that the LCM of 781,182,525,698,285 is 70690770150.
