Find LCM of 621,364,182,639,195 with Prime Factorization
| 2 | 621, 364, 182, 639, 195 |
| 3 | 621, 182, 91, 639, 195 |
| 3 | 207, 182, 91, 213, 65 |
| 7 | 69, 182, 91, 71, 65 |
| 13 | 69, 26, 13, 71, 65 |
| 69, 2, 1, 71, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 13 x 69 x 2 x 1 x 71 x 5 = 80245620
Therefore, the lowest common multiple of 621,364,182,639,195 is 80245620.
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.
621 x 364 x 182 x 639 x 195 = 5126250696840
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
182 : 1, 2, 7, 13, 14, 26, 91, 182
639 : 1, 3, 9, 71, 213, 639
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,364,182,639,195, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
364:2x 2x 7x 13
182:2x 7x 13
639:3x 3x 71
195:3x 5x 13
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 7x 13x 13 = 63882
Therefore, the value for common factors is 63882.
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 = 5126250696840/(1x63882)
LCM = 5126250696840/63882
LCM = 80245620
Thus, we can understand that the LCM of 621,364,182,639,195 is 80245620.
