Find LCM of 156,214,636,221,493 with Prime Factorization
| 2 | 156, 214, 636, 221, 493 |
| 2 | 78, 107, 318, 221, 493 |
| 3 | 39, 107, 159, 221, 493 |
| 13 | 13, 107, 53, 221, 493 |
| 17 | 1, 107, 53, 17, 493 |
| 1, 107, 53, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 17 x 1 x 107 x 53 x 1 x 29 = 436145268
Therefore, the lowest common multiple of 156,214,636,221,493 is 436145268.
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.
156 x 214 x 636 x 221 x 493 = 2313314501472
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
214 : 1, 2, 107, 214
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
221 : 1, 13, 17, 221
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,214,636,221,493, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
214:2x 107
636:2x 2x 3x 53
221:13x 17
493:17x 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 2x 3x 13x 17 = 5304
Therefore, the value for common factors is 5304.
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 = 2313314501472/(1x5304)
LCM = 2313314501472/5304
LCM = 436145268
Thus, we can understand that the LCM of 156,214,636,221,493 is 436145268.
